What program can massively replace the file extension on Windows?

Question

Windows

tell me there is a deep folder structure with a large number of actual files .
For example, you need to find all files in this structure with one extension and replace it with another. Maybe there are people who have encountered a similar case? What can you advise?

Answer 1

An ordinary batch file with a short line of code.
Create some kind of file, for example, rename.bat, write a construction in it like - Save and run. Changes the extension of all text files in the E:\Test folder and subfolders to exe. Practice on the test data, otherwise you will change something wrong by mistake ...

Answer 2

Total Commander. First, find all files by the desired mask, then display all files on a separate panel, select everything and then call group renaming (out of the box, group renaming cannot search recursively in subfolders, so you need to find files in advance and feed it to it).

Answer 3

have you tried ant renamer?

Answer 4

PowerShell

Answer 5

And I'll put in 5 cents.
There is a utility . Maybe all by renaming files.
