In case of renaming multiple file extensions to another, they suggested to type this command in cmd promt or powershell: ren *.(current extension name) *.(new extension name)
But what about to renaming multiple file extensions to nil or no file extension? How to replace this command *.(new extension name) ?
There’s also a program free for personal use called Bulk Rename. It has an incredible amount of custom options that the Microsoft power toys couldn’t do, that I needed. Just in case your program isn’t super extensive on the options and possibilities, FOSS is preferred unless necessary
