Hello, I've been having this problem off and on and lately it has become unusable. I love the way that CCleaner searches for duplicate files by content.
I am running Windows 10 with latest updates and CCleaner v5.88.9346 (64-bit).
I keep getting the "Some selected files were not deleted" error.
I have tried everything possible to fix this. I have made sure the folder and its files are owned by myself, everyone has full control, folder is NOT on read only mode. I can locate the files from the list CCleaner spits out and delete them myself, I have tried running CCleaner in administrator mode, the files are not set to compressed nor set to archived status, my log from DEBUG does not offer any useful information for this problem, multiple ccleaner uninstall and reinstall, reinstalled windows 10, I even got a brand new computer to try this on with a fresh setup, this is not caused by my antivirus or windows defender as I tried doing it on a fresh installation of windows.
The files are located on different external drives so the problem is not isolated to 1 drive.
