ClipSize

ClipSize is a simple program that shows you how much memory the clipboard is using. This can be very useful when you are using a computer with limited memory or with memory-intensive applications such as image editing or desktop publishing.

Most MicroSoft applications give you the option of clearing large amounts of data from the clipboard when you exit them – most other programs do not. ClipSize fills this niche by both displaying the current size of the clipboard and allowing you to clear it.
