Wipe free space

[Kjell arne halvorsen]

Hello. I have bought CCleaner and wonder why there are more choices on wipe free disc space when I can only choose 1 pass and not 3,7 and 35 passes

Are you looking at Wipe Free Space in Custom Clean Settings? or at the Drive Wiper in 'Tools'?

PS. You also get different options depending on if it is your system drive (the one with Windows on it) or not.

That will be because your drives are SSD's.

Wiping the free space of SSD's is not needed because of the way that SSD's work, nor is it recommended to wipe SSD's.

Wiping the free space of a drive writes data to every unused part of the drive. (Wiping the entire drive writes to every part of the drive).
SSD's have  a finite number of writes and so doing a drive wipe frequently can shorten the life of an SSD.

CCleaner will however still let you run one pass on an SSD, but it will warn you about 'wearing out' the SSD - unless you have chosen in the settings to hide warning messages.

PS. There is no need to use more than one pass to wipe any drive these days, whilst multiple passses used to ocasionally be prudent years ago that is no longer the case.
The multi-pass options are still there in CCleaner for HDD's simply because they are left over from years back, and because some people do still believe that it is somehow an advantage to empty the same space more than once.
