What files can or should I delete? (Temp files, cache, binaries...)

Hi,
Intermediate saved and binaries work fine!!
Fix redirectors work fine too!! This help a lot!!

But, migrate levels was a disaster!! I lost the project settings. And the files were moved to random directories…

I think to remove the some files from the original project combined with your first and second options can be the correct way to do it…

Thank you so much for you help!!
