How to change the extension of a file

 

There is different methods to change the extension of a file. Changing the extension name can be done by different methods. Some methods will work on some files but not others.

The naming convention of a file is as follows

Joseph.JPG

Joseph - is the filename of the file

.JPG - is the extension of the file

 

Change name via Windows Explorer

  1. Open Windows Explorer

  2. Go to the location the file is at

  3. Click on the filename of the file till the filename is highlighted.

  4. Type the name and extension that you want the file to have

NOTE: Some files will not work by this method. On the files that don't work in this method, you would need to open it in a program that will change the file.

 

Change the filename or extension using a program
