Does a given CCleaner backup file contain deleted cookies and cache info... ?

... or is it just a backup of registry items removed?

I'm not particularly tech savvy (obvious no doubt; sorry) and got a little nervous when trying to open a CC backup file in an attempt to view its contents, in search of deleted cookies and cache from a given date.

Any help appreciated, thanks in advance. :)

only registry as the backup option only appear when cleaning registry, not file

If it has a ".reg" extension you can right click and select edit or you can open it with notepad.

That will let you see the contents, but as dvdbane said it will only be registry entries.

Be careful, don't change anything in case you want to put it back into the registry later.

If you double click it it will just offer to merge itself back into the registry.

Thank you both for the help!
