If you're looking for an agile, do-it-all disk cleaner and optimizer, Wise Disk Cleaner Free isn't it. It is, however, a reliable freeware application that may surprise you with its quick scanning pace and it's optional wizard that guides you through the process of naming and taming unnecessary, space-sucking files.
You'll be able to include or exclude the file types scanned and he location on your drive. Pay close attention to the Options menu that lets you sanction temporary files and folders and broken shortcuts--you may want to spare something that's herded in by default. As you would with any system astringent, take care when scrubbing a specific folder, and when fixing problems. Thankfully, this disk cleaner program wisely lets you delete files to the Recycle bin, where they're ultimately recoverable. Elect to permanently delete them, however, and they're gone.
Wise Disk Cleaner Free is simple, has just enough options for more serious users, and can quickly make a difference in streamlining your system for speed.
