how to fix file path too long error in Windows?
The error comes from the 260-character API limit that many programs still hit even with long paths enabled in the registry. longpath performs the copy, move or delete through extended-length paths, so the operation succeeds without renaming your whole archive first. It is a 100 MB portable exe, MIT, and it previews every change before touching disk.
