Hello All,

I've got a USB memory stick whci I carry with me and plug in to different
computers. Al of those systems standardly assign the first available free
drive letter to it, which often differs between them. This means that I
have to figure out for each of those systems which drive letter my stick
got, and remember to use that one for as long as I'm on that computer --
only to rehash that process when I get to another one.

So, my question is: can I refer to the USB memory stick by something else,
unique to the stick itself. Maybe the volume name ? I was thinking
something like :

\\{volume name}\path\file.ext

Remarks:
On the above computers I do not have the permissions to select a persistant
drive letter for my stick (I'm a user on them, not an admin).

I also wrote a one-line batch file which first finds my stick, and than uses
SUBST to make a symlink to the drive letter I want, but that means I always
have to run that batchfile first. Also, when ejecting the stick the
SUBST'ed drive remains ...

You mean volume GUID and not the volume label, right?
It possible to uniquely refer a disk volume by its volume GUID, but the GUID
is random and will be different accross different PC.
Moreover, with volume GUID, you won't be able to get a list of a directory
contents.
