A Replacement Windows Explorer. With Tabs! [1]

If you like playing with replacements for the standard Windows Explorer, you might just love this one for a number of reasons.  First, it's a tiny download of just half a megabyte.  Second, it doesn't need installing.  Just unzip the downloaded file and click on the application to run it.  So if you don't like it, removing it from your PC requires nothing more than deleting the file. Third, it's open source and free.  Fourth, it comes in 32- and 64-bit flavours. 

And finally, it's got tabs.  So you can have more than one drive/folder/directory open at a time, and easily flip between them.  Which makes it really easy to explore your hard drive, open applications, and keep your hard drive tidy.

Explorer++ runs on Windows XP and above, and you can get it from www.explorerplusplus.com [3].
