The Recycle Bin provides a safety net when deleting files or folders. When you delete any of these items from a hard disk, Windows places it in the Recycle Bin and the Recycle Bin icon changes from empty to full.
If you have multiple hard drives, partitions, or an external hard drive connected to your PC, each location will have its own $Recycle.Bin and Recycle Bin settings. Removable drives, such as USB flash drives and memory cards, will not have a Recycle Bin. Files deleted from removable drives are permanently deleted.
Items in the Recycle Bin still take up hard disk space and can be undeleted or restored back to their original location. When the Recycle Bin of a drive reaches its maximum storage size, Windows will automatically permanently delete (empty) older files in the Recycle Bin location to accommodate the most recently deleted files and folders.
When you manually empty the Recycle Bin, all files in the Recycle Bin deleted by your account will be permanently deleted to free up disk space.
If you are unable to empty the Recycle Bin or delete an item inside the Recycle Bin, then the Recycle Bin may be corrupted.
This tutorial will show you how to fix a corrupted Recycle Bin in Windows 7, Windows 8, and Windows 10.
