There are times when you need to change multiple files extensions without renaming each and every file especially if you downloaded more than ten files where the operation of changing their extension becomes exhausting. This tutorial presents an easy method to perform such an operation, it may be easy for some but it is surely handy for others.

1. First of all put all the files inside a single folder.

Put The Files inside on single folder

2. Open “notepad” and write the following: “rename *.txt *.zip” where you can change “txt” to the original files extension and the “zip” to the intended extension.

Rename *.txt *.zip

3. Save the file as “rename.bat” in the same folder. Be sure to choose “All files” from “Save as type”

Save As

4. Open “rename.bat” and all the extensions will be changed.
