normally i havnt done the backup while using CCleaner (couple of years) but after reading one of these posts i think i should start so my question is 'when i make a backup and it saves to documents (by default) then do another bakup the next time i use CCleaner does it automatically over write the previous backup or do i delete it manually?'.
you have to delete it manually
No it doesn't overwrite the previous one.
Each backup contains backups of the reg entries that you have deleted at a specific clean and can be recognized by the date.
They are not backups of your whole registry, just a backup of reg entries you cleaned at a specific point in time.
@winapp2.ini & hazelnut thanks for your reply ill now backup when cleaning
