The Disk Cleaner has two main functions: Duplicates and Junk Shredder.
- Duplicates - This searches for any duplicate files you might have on your device, which can use a lot of space, and lets you delete any you don't need.
- Junk Shredder -This searches through folders looking for junk data that can slow down your device. The main folders checked are Cached Windows Updates, Recycle Bin, Temporary Files and Windows Error Reporting Files. These files can often take up a lot of space.
