Comodo Disk Cleaner generates a backup of the folders/files deleted during Disk Cleaning operations if the option Backup Files before Cleaning in the Disk Cleaner > Settings is selected.
The backups are stored in date and time stamped folders in the location of your choice. You can store the backup files in your computer locally, on a computer in your network or even in an FTP server. This back-up function enables you to restore the registry to a previous state in case you encounter some system failure or if you want to undo any changes To understand and manage your Comodo System-Cleaner backup please visit Settings > Backup Settings section.
You can disable this option in Settings of the Disk Cleaner.
Note: COMODO strongly recommends not to disable back-up option.
