@Mistuke what might cause

      Exception: tests\IntegrationTests2\regression/3324\q\q.cabal.backup: renameFile:renamePath:MoveFileEx "\\\\?\\D:\\a\\cabal\\cabal\\cabal-install\\tests\\IntegrationTests2\\regression\\3324\\q\\q.cabal.backup" Just "\\\\?\\D:\\a\\cabal\\cabal\\cabal-install\\tests\\IntegrationTests2\\regression\\3324\\q\\q.cabal": permission denied (Access is denied.)

Writing to that file is ok, is it somehow held open, so cannot be renameFiled to?

And how one can force closing etc. properly, so file can be restored?

Yeah, It's usually an indication that the file is open somewhere with an exclusive lock. The lock is only released when the last handle to the file is closed.

The handle may not be opened by you, it may be held by another process (antivirus, or indexing service for instance). I would look at whatever produced the backup file to see if closeHandle was actually called.

Things that remove/move files we tend to add a retry loop for haskell/hsc2hs@0f68aff it's short and in most cases won't loop, but if something has it locked it'll usually get freed pretty quickly.

@Mistuke thanks for the hsc2hs link, that helpful (currently I just do nothing, as it's only tests, so if file isn't not reverted to the original, it's not a big issue).

Windows really makes some "easy" things really cumbersome.

Yeah, it's all a consequence of layering over time. I tried to get some support for this in stuff like directory but some people have been rejecting the idea. I might just do it in Win32.

there's removePathForcibly, that's already something. If there's similar-ish "best-effort" thing for moving files, it should be in directory (maybe not as renameFile). Reinventing things is very consuming.
