After all that, i still can't remember which is the slash and which is the backslash =P
When i say a drive name to myself i say "C colon backslash," and when i type it i type "C:\", so i think that might be the backslash, but i know there are contexts in which you use the other one (windows vs unix i think? I don't always remember that offhand either, i just look at what's being used for the context in question and use that) so i may just be confused. It would make a lot more sense to me if they called them "upslash" ("/") and "downslash" ("\") because both of those are pretty clearly going forwards to me and there's no backwards component at all to either of them.
There's a lot of stuff about computers that i don't know and really should, but that's got to be the most trivial item :)
