All files and folders sent to the Windows Recycle Bin may disappear from the folder tree, but Windows still stores them on your PC hard drive and keeps track of them. Eventually, one of four things will happens:
1. You can eliminate things in the Recycle Bin, either by emptying it or by deleting some of the files and folders there.
2. The Recycle Bin gets full, and starts permanently deleting its oldest files to make space for new ones.
3. You turn off the Recycle Bin so deleted files aren't put there anymore.
I will cover all these possibilities. and in addition, will tell you how to streamline the deleting process, if you want to do so.
The Windows Recycle Bin has properties. To display them, right-click the Recycle Bin icon on the desktop, and choose Properties from the shortcut menu. The Properties dialog box contains a Global tab, plus a tab for each partition of each hard drive on your system.
