Viewing the total size of all files that have been deleted to Recycle Bin in the good old Windows XP was a dead simple task. In Windows XP, the Status bar would show the total size of all files in the Recycle Bin when you select all files.
Unfortunately, none of the recent versions of Windows, including Windows 7, Windows 8 and Windows 8.1 show the total size of all files in the Recycle Bin when you select all the files in the Recycle Bin. The status bar shows only the total number files that you have selected.
In order to view the total size in recent versions of Windows, you need to right-click on the system drive (Windows installed drive), select Properties, and then perform a disk cleanup task.
Fortunately, users who have updated to Windows 8.1 Update can view the total size of all files located in Recycle Bin without having to open Disk Cleanup tool. However, unlike Windows XP, Windows 8.1 Update doesn’t show the total size when you select all files in Recycle Bin, and instead, you need to navigate to PC settings to get the information.
