The Windows file deletion dialog and its “Discovering files” process.,(reply>), @Ståle Exactly! I hate it so much! xD,(reply>), Well it doesn't know how many files there are yet so it can't know how many there are left!,(reply>), Explorer in general and NTFS are terrible at dealing with large file counts.,(reply>), For high enough file counts, you're 100% better off deleting from within a command prompt (or better yet Linux shell if you have cygwin/WSL) than letting it finish that discovery process.,(reply>), It's like when you decide to throw away everything in your attic, but end up unpacking it into your living room instead
