i run CC Cleaner about once a month on our computer (just to clear out the rubbish)
Problem i'm having is that we have 6 user accounts on our computer and i have to go into each account to clean them.
I've looked in the options to set the cleaner to clean every account in 1 go but am having problems.
When i try to add a folder i get a message saying:
Warning!
This folder will be emptied of all files upon cleaning.
Are you sure you want to do this.
What does it mean by... all files??

i have been to the C Cleaner website and have found this information

Still not sure what is meant by....All Files though.
But at least i have the main question answered.

It means that all files in the folder you add will be erased along with any folders in that folder, leaving an empty folder. If you scan with CCleaner you can go through the list to see what will be removed. If you see something you do or don't like in the list, close CCleaner without making any changes and go back to the options and make the adjustments.
