In the information world, there are more than a dozen different text formats. Most computer users use Microsoft Office to work with text files. Extensive functionality, ease of editing of almost all known formats and constant updates have made Microsoft Word the most popular document editor. Since there is no single format for text files, users often have questions about how to change the format of a text document. Faced with an "unreadable" format, or do you urgently need to change the format? ..
Before you start changing the file format, you need to understand how the document format differs from its extension. The format is the content of the file, and the extension is just a bunch of letters that tell the system which program to open the file with. For example, if a file has the extension .avi, then Windows will open it with the default video player.
Change the format of Word documents
To change the format of a text document, it is recommended to use the built-in features of the Microsoft Word editor. Open the document in any version of the Office, click on the "File" button at the top of the screen and select the "Save As" tab.
In the drop-down list, specify the format in which you want to save the file. Select where to save the new file and click "Save".
In this way, you can "translate" any Word document into the desired format.
Change txt file format
If you need to change the format of the txt file, it is much easier to change the file extension. But first you need to enable the display of extensions in Windows. Open My Computer and press the Alt key on your keyboard. In the line that appears, click on the "Service" button and go to the "Folder Options" tab.
In the new window "Folder Options" go to the "View" tab, scroll through the "Advanced Options" list to the end and uncheck the "Hide extensions for registered file types" item. Then click the "Apply" button, followed by "OK".
Click on the text file with the right mouse button and select "Rename" from the context menu. For example, if a text file in .txt format is changed to .html, then the file will already open in the browser.
In the same way, you can "translate" a txt file into .doc or .rtf format. But if you try to rename the extension, any Word document in .txt will have problems opening the file.
If you don't have the Microsoft Office suite at hand, you can use special conversion utilities or online services.
Imagine:
- file is in front of you. By double-clicking, Windows offers to choose the program with which to open it. And who knows what kind of file it is, what extension it has and what program can open it
- Dangerous situation. The file greetings.jpg came to you by mail. You decide it's a picture and you open it. And the true extension, as it turns out, was hidden from you - the file was called greetings.jpg.exe and was virus!
- The file came by mail again. Exactly the executable file with the extension exe that you are waiting for. But the mailer for security purposes (as in the previous paragraph) renamed the file, adding the safe extension to it. You are trying to rename a file, but you are not offered the option to change the extension. How to run the file is unclear.
- you have two files on your desktop and look exactly the same. Both the names are the same, and the pictures are the same. And one of them is doc and the other is rtf. It's time to get confused.
In these cases, you just need to enable display
Or a situation like this:
- you downloaded the archive from the Internet, but for some reason the browser saved it with htm resolution (web page resolution). Naturally, you will not be able to unpack such an archive.
You need change file extension to the correct one.
What to do in this case?
- Specify the display of extensions in the Windows settings.
- Use a file manager.
You can change the formats (extensions) of some files by simply renaming them.
However, Windows may not show the file extension, including for security reasons, so that the user does not inadvertently rename the file incorrectly. Those. in your explorer, the files are displayed like this:
To change the file extension you need enable the display of file extensions in Windows.
1.How to set the display of file extensions in Windows settings
We go to the menu: " Start "-" Control Panel ".
There are two options here:
a) you have included the classic style
In the case of an active classic style, immediately select "Folder Options".
Then we select the item "Designs and themes".
And in the next step, we also select "Folder Options".
In the properties, on the "View" tab, we find the item "Hide extensions for registered file types" and uncheck the box next to this item. Click "OK".
You can also open the display of file extensions via Windows explorer (double click on the "My Computer" icon on the desktop or the keyboard shortcut Win + E). Go to the folder where the file you want to change is located. In the Explorer menu Service select item Folder properties. IN Windows 7 there may be no menu; in this case, press the Alt key in the Explorer window and it will appear. Menu item equivalent to Folder properties in Windows 7 is called Folders settings .
 |
(note: in Vista, the main menu item is called "organize", and "folder properties" can be found in the control panel (start - control panel))
On the "View" tab, uncheck the box next to the "Hide extensions for registered file types" option and click the "OK" button.
Now you can see that the names of the files have changed, and the names of their extensions appeared on the right after the dot: "flv", "jpg", mp3 and so on.
or select the required file and press the "F2" key on the keyboard (analogous to the "Rename" command).
Delete the old extension to dot and enter the new extension instead. Remember that you should not touch the dot, otherwise the extension will merge with the file name. After the new extension is indicated, press the "Enter" key on the keyboard.
The Windows operating system will give you a warning window that after changing the extension, the file may become inaccessible. Click the button "Yes" to confirm the change.
This will change the file extension.
And now on the desktop you can see graphic icons of files with an indication of its extension
If suddenly the file stops opening, just put the old extension back in place. This usually helps to correct the situation.
And here is a video tip to help you:
If you want to know what an extension means, take a look at filetypes.
I recommend not hiding file extensions on your computer if you are not familiar with them yet. Open file extensions will help you quickly learn which extension belongs to which type of file, and if you come across a file-virus, for example, a picture comes by mail, and its extension is EXE or BAT (executable files), then you will never open such file.
Also, file extensions are often shown by default in many file managers, for example, Total Commander.
2.How to change file extensions in Total Commander
In Total Commander, extensions are listed in the second column of the disk window.
To rename the file, press Shift + F6 and just write a new extension.
After that, do not forget to press Enter, and the file changes its "surname". Now flv video as mp4 can be safely uploaded to LiveInternet.
And finally:
Remember! As a rule, changing file extensions often makes it impossible to open and edit them in the future. Therefore, you need to be very careful when experimenting with extensions. However, some file extensions change without much effect, for example a text file with a txt extension can easily be turned into an html web page that opens in a browser.
It is best not to resort to changing file extensions, but to save files in the desired format, use the "Save As" command, which is usually located in the "File" menu of all common programs. For example, you can save a Word 2007 document with the docx extension in the Word 2003 document format with the doc extension. A simple change of the document file extension using the "Rename" command will make the docx file unreadable.
Based on materialsBraveDefender, yachaynik.ru,
An extension is a set of characters after a file name that define its purpose. Thanks to these symbols, the personal computer understands what actions must be taken when starting this object. For example, “test.txt” is a text document, “qwerty.html” is an HTML markup page, and “track.mp3” is an audio recording. It is the words after the period (".txt", ".html", ".mp3") that tell the computer about the type of information stored. This article describes how to change an option such as file extension in Windows 7.
Why is this necessary?
There are many reasons why users might want to change the object type. However, all of them are rarely used in everyday life and are used mainly by computer specialists and web developers.
The most striking example of a reason to change a file extension is the creation of a bat file.
A bat file is a small program that can be written even by an untrained user, which sequentially executes a set of Windows console commands. For example, you can make a bat that will remove the "Hidden" attribute from all objects in the current folder by placing just one line "attrib -h / s / d" in it.
However, it is impossible to create a document with the .bat extension through Windows Explorer. Therefore, users take a plain text (.txt) document and edit it, after which all that remains is to change its type. The following article details how to change a file extension in Windows 7.
Configuring File Explorer
In order for inexperienced users to not be able to change the parameters of any important files for the operation of the system by their random actions, this function is disabled by default. Therefore, first you need to activate it:
How to change the file type
After the above steps, the name of each object will be displayed and its extension. In order to change it, users need to right-click on the file, select "Change" and replace the old type (2-4 characters after the dot) with a new one. 
| Expansion | Description |
| txt, docx, rtf, odt, doc | text format |
| mp3, wma, wav | audio extension |
| msi, exe | extension of executable files |
| avi, flv, mov, mpeg, 3gp, ogg, mov, vob | video extension |
| jpg, jpeg, jpe, bmp, gif, png, tiff | picture format |
| pdf, djvu, fb2 | e-book format |
| zip, rar, 7z, | expansion of archives |
| html, htm, xml, asp, php, css | web pages |
| csv, xls, xlsx, sxc | extension of spreadsheets |
To change the file extension in the Windows7 operating system, do the following:
- open "Start" \u003d\u003e "Control Panel".
- select the view type "Small icons" \u003d\u003e "Folder options"
.
- after clicking "Folders settings"
a new window will open. Go there to the tab "View" and remove the bird from the point
.
Click "OK"
.
Now everything is ready to change the extension. You just need to right-click on the desired file, a new pop-up window with a list will open. Select from the list "Rename".
After you clicked "Rename", it becomes possible to change the file extension. Just remove the old extension to dot and write a new one.
How to change the file extension Windows XP.
In Windows XP, the ability to display the extension is enabled in a slightly different way than in Windows7, but you can change the file extension in the same way.
- go to any folder and select from the top menu "Service » =>
«
Folder property "
.
Then a new window will open, the same as I described in Windows7. Go to the window by tab "View" and remove the bird from the point Hide extensions for registered file types
.
Click "OK"
.
Everything is ready. In order to change the extension, do the same operation as I described for Windows7. Right click on the file, a new pop-up window with a list will open. Select from the list"Rename".
Remove the old file extension before the dot and write the new one.
The advantage of Total Commander is that all files are displayed with an extension at once and no special transitions are required to see the format. You can change the file extension using Total Commander very quickly. Now you will see this with an example.
Open the file in which you want to replace the extension in Total Commander.
After pressing the F2 key, you will be able to change, delete, change the name and extension of the file using the standard method. When we have made a replacement, click "Enter" .
That's all. If something is not clear to you, write in the comments, I will answer quickly. If you liked the material, tell a friend by clicking on the social media button below. ABOUT!!! I almost forgot: subscribe to my blog updates so you don't miss out on fresh, useful topics.
In this small but useful post, I want to talk about how to change the extension of any file on your computer. And if in windowsXP this procedure is unlikely to cause difficulty for anyone, in windows7 everything is a little more complicated. The file extension is often hidden from editing there.
Someone may have a question - what kind of extension are we talking about? If we take any file, for example a Word document, we will see that it is written something like this - "Change the file extension ..doc". All that comes before the period is the file name, and what comes after the period (.doc) is the file extension. Extensions play a very important role, they help the operating system recognize the type of file and determine which program is best to open it. Extensions are very different - .txt, .iso, .jpg, .rar and many, many others. Accordingly, there are programs and applications for reading each of them.
It is often necessary to change the extension. For example, when editing a printer's color profile, we had to change the .icc extension to .icm. Otherwise, Color DarkRoom would simply not recognize the file.
In windowsXP, the extension is easy to change. Right-click on the required file and select Rename. Now both the file name and its extension can be easily changed using the keyboard.
But in windows7, during such actions, only the name is often edited, and the file extension is hidden. In this case, you can do it in several ways.
1. Click on the Start menu (the circle with the logo in the lower left corner). At the very bottom, in the search form, enter the Folder Options and select the line with this name from the list. In the window that opens, on the View tab, uncheck the Hide extensions for registered file types line.
Now you can change the extension in the usual way, as described above.
2. In the second way, we do this - open any folder on the computer and in the upper left corner, click on the Organize button. In the menu that opens, select the Folder and Search Options line, by clicking on which we will again see the window familiar to us in the first method, where on the View tab we uncheck the Hide extensions for registered file types line.
There are a couple more ways to change the file extension in windows7, but I think these are enough for you.

How to change file extension in windows 7 and XP?
Today, dear friends, we will analyze a very important issue that interests a huge number of computer and laptop users. But before we start talking about this, let's find out what an extension is and why it needs to be changed. Let's go in order.
The extension is necessary so that the operating system could quickly determine which type of format a particular file belongs to. Let's say you have uploaded a photo.jpg to your desktop. If the system did not automatically detect the extension, then each time you see a photo, you would have to manually select the program through which this image would open. Difficult, agree?
Why might you need to change an extension? Here's a simple example: you have m4a files on your computer that your iPod can't read at all. What to do in such cases? Alternatively, you can use special programs that allow you to rework formats. However, such programs are often expensive and take up a lot of free time. Therefore, the best solution can be considered a simple change of the extension, because the file itself does not change from this, but the iPod can easily read it.
Changing the extension using the standard method
Let me tell you right away, friends, that there is no fundamental difference in this matter between the operating systems windows XP, Vista or 7, so we will show an example based on the latter of them.
Open the "Start" panel - "Control Panel" - "Folder Options".
A new window has opened in front of you. Select the "View" tab and scroll down until we see the inscription "Hide extensions for registered file types." Uncheck the box next to it and then click "Apply" and OK.
Now what? And now we go to the desktop or to the folder where the required file is located, select it, right-click it and select the "Rename" item from the menu. Now you can safely change the file extension to whatever you need. As you can see, the whole process took only a minute of your free time.
As for windows XP, the folder settings section in this operating system is not in the control panel, but in the "Tools" section (open any folder and you will see it in the top menu). Otherwise, there are no differences.
Using the file manager
You can always use the file manager if it is installed on your computer. As a last resort, such a program can be downloaded on the Internet - they are distributed, as a rule, completely free of charge. In this case, we will show an example based on Total Commander.
Open your file manager, select the drive and folder where the file is located. Move the mouse arrow over it, select Rename and change the extension.
We use WinRAR
This method is designed for the most real maniacs and you can use it only for your own satisfaction, since it is too unusual, although simple.
Surely most of you have WinRAR installed on your computer to archive and unzip files. It will be useful to us.
Take the file and zip it using WinRAR. Then open the archive, select the required file, change the extension and unzip.
We hope we helped you with the answer. If you have any questions or any advice, do not hesitate, post them through the comments, we will be interested in reading them. Sincerely.

How to change file extension in windows 7 and 8, step by step instructions
The information stored on our digital devices can be in different formats. Many users periodically face the question - how to change the file extension? This need is periodically due to the need to translate an image into the desired format, adapt a document downloaded from iTunes and other mobile content stores to fit the device, reformat text content into a web page, and other reasons. How can you change the extension so that the information retains all its properties? Let's try to figure it out.
What is the extension or file format
Before changing to enable the function of replacing an extension, the user needs to know what it is, what this characteristic affects:
- First, it limits the range of applications with which you can open the file.
- Secondly, it was created so that the device can determine its type.
Each of the documents has its own format, which is indicated after the title. Using this property, the system determines what type of information it deals with - video, audio, etc. The extension characterizes this parameter and helps the system to choose the most suitable application for opening. Before changing the file properties to suit your needs, you need to remember how to find out the format, and only then think about how to change the existing file extension.
To do this, right-click and select the "Properties" tab. The extension will be listed in the "File Type" line. In most cases, this property looks like a combination of 3-4 letters and numbers. By way of illustration:
- audio files come with the mp3, wma extension;
- video files - mpeg, avi;
- graphic images - gif, jpg.
When the system sees this letter combination, it understands with which program to open the file and, as a rule, can decrypt it. When changing the format, it is very important to correctly perform the algorithm of actions, taking into account the peculiarities of a particular operating system, otherwise you can damage the information by specifying an incorrect format, and in the future the system simply will not be able to perform the decryption procedure, etc. To prevent this from happening, we have prepared for you step-by-step instructions on how to change the extension for different OS and other useful tips.
Some files do not have any extension and the easiest way to change their format is. The user needs to right-click, select "Rename". Then a period is assigned to the name, after which the literal value of the extension of interest is entered. If the properties after renaming fully correspond to the required format, the information will be opened by the required applications.
By operating systems of the windows family, the extension is hidden from users by default. The ability to convert a file is provided by one of the sections of the control panel. By entering and making the appropriate changes to the settings, you will be able to give the files you are interested in the desired format. The procedure has some differences for different versions of the operating system. Converting information is not such a difficult process, and its implementation is available even to users without advanced skills.
