For S & G's, I did a googling about drive letters, to see if there was anything out there about A and B drives that didn't have to do with older computers usually having one or two floppy drives... Nope, that's the real deal. No other mystical explanation. (Most people don't realize why IP addresses are four quads of 0 to 255... ;) ) Anyhow, in reading the pages I found, I discovered something VERY interesting about SUBST. For those of you who do not know, SUBST is a DOS command (but works in XP and Vista too), that allows you to 'create' a virtual drive off of a physical folder. For example, let's say you have a network drive 'T:' at work. And you have an application that depends on files being at T:\SomeFolder\*.* . Well if you create a folder on your C: drive, and call it TDrive (Thus C:\TDrive) then copy that 'SomeFolder' into that TDrive folder. Then, from a DOS prompt, you can put in: SUBST T: C:\TDrive And Whalla, you now have a T: drive, that is really the 'C:\TDrive' folder. Anywho...the neat thing I found out about SUBST that I never knew, is that SUBST actually let's you use non-alpha (some of them...) characters to create these 'virtual' drive letters. They don't appear to show up in Explorer though (at least not in Vista). I have a folder on my C drive called 'Downloads'. So in a dos prompt, the following command: SUBST $: C:\Downloads Allowed me to then go: $: Which gave me a: $:\ Prompt, which I could then do a DIR in, and it listed the contents of my 'money' drive! LOL Ok, I'm a geek! ;) Drew -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Max Wanadoo Sent: Friday, February 06, 2009 1:29 PM To: 'Access Developers discussion and problem solving' Subject: Re: [AccessD] OT: I'm old Was I right then?
