Just saw it doing work on a machine upgdg.. see it makes crazy set of directories & subdirs named in iterations of zz. Then it mzkes one big file of random name and grows it. Good to know it is filling it with zeroes

Ah sounds good just been getting sector copy images of same disk dropping from 150 to 200 gb down to 10gb, a 400gb drive down to about 8gb !! Used ccleaner on another machine about to prep so am happy don't need to lose a few hrs deleting it Fab

Oops seems this damn tablet has let me put posting in wrong section. Moderators plz rectify

Qquestion: What method does cleaner use to wipe disks? I we that it is fast. .. having just used delete cmd line. Reason I ask is not security Q...... it is about space & compression. With the win10 deadline approaching I am doing a lot of disk imaging at diff stages to backstop any probe (had a dual switchable gdfix laptop that caused headaches)...... and having a shock when a supposed empty disk is making v large images. Zeroing the free space means MACRIUM GHOST ACRONIS etc just sees a large block of zeroes and squashes it to next to niL...... much quicker too. So zeroes or random? Roadkill blanking util v slow. sdelete not too slow. Any typos sort blame wretched tablet & predictive overrides.
