I have certain files that have not been accessed for a long time, but have not been cleaned up.
If your Folder Integrity set to "Preserve the entire parent folder" or "Preserve the entire root folder", expired files are kept when other files in the folder have not yet expired.
Why is the cleanup process so slow sometimes?
When Time Machine or other software scans the disk, the cleanup speed slows down.
There are tens of thousands of files in my folder. Why is the cleanup process prompted to scan only thousands of files?
Depending on the scanning rules, if a file is determined to be preserved, it is possible that the other files in the same folder will not be scanned.
Can I quit the AutoCleanFolder App while a cleanup is running？
Yes, cleanup tasks are performed in the background.
