It would be nice if you could get the program to save the settings to another drive so you do not have to spend a lot of time re-setting cookies and other settings when reinstalling a computer because you can not backup ini files with backup applications
In options you can use ini for settings (don't remember the actual words). Then you can copy that ini into other ccleaner instances.
I thought it was possible to have the very current setup if one computer broke down, since no backup program will backup ini files
If a particular backup program won't save the INI files into a backup you could instead create a .BAT file to copy the files elsewhere such as to another hard disk, or even use a ZIP program to backup the file to elsewhere.
Example:
copy /v /y "%ProgramFiles%\CCleaner\ccleaner.ini" "E:\Backups\CCleaner Backups"
