I previously recommended PhraseExpress for similar clipboard management functionality, but I’ve since switched to Clipdiary (available free via Clipdiary.com or Download.com) for a couple of reasons – first, that PhraseExpress would randomly lock up and prevent me from using my Enter key (weird, huh?), and second, because ClipDiary is super lightweight and does exactly what I want it to do. Here’s a blurb from their website:
The contents of the standard Windows clipboard change as you use it to copy and paste various types of information. But your data isn’t stored for a long time – when you turn off the computer or just copy another piece of information, the data is lost.
In most cases, that isn’t a problem, but have you ever needed the text you copied 30 minutes or an hour ago? Maybe your computer is acting up and the program you are using hasn’t saved the data, or maybe you copied some interesting information from a web page, but got distracted and forgot to paste it where you wanted? Or you may simply want to recall what you were doing on your computer a month or a year ago. There are many cases in which you might want to review your clipboard contents.
