How to Change the File Extension on a Lot of Files at Once in Windows
Changing the file extensions of multiple files in Windows is not possible with any native tools. In order to complete the process, you have to download a program, which is free, called "Extension Renamer." Windows only allows you to change the file extensions of files one at a time, whereas you can select batches of files with Extension Renamer and change their file extensions.
