How to Change File Extensions in Bulk with Command Prompt

Sometimes you may need to modify the file extension of lots of files at once, and it can be easily done without any issue using the command prompt. You can also use third-party tools to change file extension or entirely change data type with converts if you are dealing with audio, video or image files.
