Overwriting CCleaner passes.

Question

If you run 35 passes with CCleaner and wipe free space, then if it finishes and you run it again back to back, does it mean you have wiped it 70 times or does it ignore what has been wiped and look for new stuff?

Answer 1

The passes won't double if you run it the way you've mentioned above. Also, the developers created a page with details regarding the Wipe Space function found in the CCleaner application.

Here is the page: https://www.piriform.com/docs/ccleaner/using-ccleaner/wiping-free-disk-space

According to the page, there are the limitations regarding the Wipe Free Space:

• The file has been overwritten by another file (so no need to overwrite this again)
• The file had been overwritten by another file before you ran CCleaner, but the second file has now been deleted as well.
• The file was created almost exactly when you ran CCleaner.
