Trick for command-line junkies
I'm still very much a command-line kind of guy. I get around the Windows UI just fine, but frequently I find it quicker to just drop to a command prompt to accomplish certain tasks (especially since Explorer generally sucks at launching apps with command line params). I like the "My Documents" feature of Windows, as it keeps documents easily accessible in from the Windows Explorer. However, when I want to perform a command line operation in My Documents, it's a pain to navigate there, even with path completion. Plus, C:\Documents and Settings\Kevind\My Documents is a long string, so my cursor starts 2/3 of the way over in the window before I've typed a single character.
I recently hit upon the idea to create an NTFS junction point off the root directory (I called in mydocs) that points to the "My Documents" directory. I used the Junction tool from the wizards at Sysinternals. It worked like a charm, and made "My Documents" much more accessible from the command line. Of course, this solution wouldn't work too well on a machine that is shared amongst multiple people. But for me it works peachy.
