Wondering where all your hard drive space has gone? There's a good chance you can get at least some of it back. And Wise Disk Cleaner Free can help by scouring your system, looking for junk files that can be deleted.
Unlike most of the competition, the program doesn't simply wipe the contents of predefined folders (recycle bin, temporary files, browser cache and so on). Instead it searches your entire hard drive, looking for temporary or leftover file types.
The good news about this approach is that Wise Disk Cleaner Free is very thorough, and can uncover junk that other tools might miss. But the bad news is that it's slower, and there are risks involved, because identifying what can safely be deleted is very difficult. The program assumes that anything with a .CHK extension is a scandisk remnant that can wiped, for instance, but a .CHK file can also be a database checkpoint that really shouldn't be deleted.
Don't let this put you off Wise Disk Cleaner Free altogether, though. In just one click you can tell it not to detect .CHK files, and you'll be safe from accidental deletions. But even then, we'd recommend you check every file the program lists before you delete it, just to be sure you're not erasing anything important.
Version 9.31 (full changelog):
A thorough way to detect junk files, but beware - this isn't for beginners. The program may also recommend that you delete legitimate files, and you'll need the expertise to tell the difference
