OT: Why does XP choke on the filename - "com1.gif"

Hey, it's Windows.  What did you expect?

I was able to name a folder com16 or some such, btw...

Apparently Windows only blocks the names for ports which actually 
exist.  Makes sense, but what happens when I put my "com16" folder on a 
disk and stick it into a Windows box with 16 or more serial ports?

Actually, I'm going to try making a "com1" folder on a CD (from my Mac) 
and inserting that into a Windows box.  Hmm...

Well, Windows 2000 sees this as not a problem.  You can look inside the 
empty folder and everything.  Same with XP home.

Note: In XP home, creating the empty folder on the desktop and naming 
it "com1" results in Windows quietly switching the name back to "New 
Folder" with no error or anything.  W2K at least complained that the 
file already existed.

Strange inconsistency.
