I've used Photorec on my hard drive to find deleted .jpeg photos, and as someone said elsewhere, it recovered images from long ago.Total nearly 3000 ! BUT most of them were images I'd never downloaded/installed;eg Small images of nearly all the government, the Royal family, Michael Jackson, and icons from various websites, or book covers.How did they get there ? Surely they take up room on the hard drive that could be used more usefully ? Can I delete them permanently somehow without formatting the drive ? I was the more surprised as I have a defrag program working in the background when the PC is idle, which I thought would make them irrecoverable.Can anyone enlighten me ?
The only way to actually delete files ie. pictures is to re-format your harddrive, as a normal "delete" just allows the file to be written over, however if you wish to make these files un-readable, free software such as "file shredder" enables you to over write the "free space" on your drive with layers of "gobbldegook" to make them un-recoverable. Hope that helps.
Thank you both.I've now used CleanUp and deleted many items.(I used it in demo mode first)It's something I wouldn't want to use often as it deletes not just the temp files but the cookies for my homepage and others I visit regularly.It's a pity you can't specify files to keep as with CCleaner.I'm surprised Ashampoo Winoptimiser7 hadn't deleted them all.I wonder if the offending pics I had were indeed temp files as they were .jpg and not .tmp. CleanUp didn't list any .jpg files to delete , so would they still be there? (I don't want to use Photorec again to find out.)
