Recycle Bin accommodate the files you delete and lets you recycle deleted items. When someone deletes any file and or folder it is moved into the recycle bin. By default, it will take up to 5% of free disk space on the drive.
To delete an item, you right-click on it and select Delete. This will delete the file or folder and move them to the Recycle Bin. If you press the Shift key while deleting the file or press Shift+Del key, then the item will not be moved into the Recycle Bin. It will be deleted permanently.
