Truename gives the "fully qualified filespec" for the filespec that follows.
So from my D:\TMP directory "truename ..\screen.cut" gives D:\SCREEN.CUT.
And on a network or CD-ROM drive, you get stuff like \\name\volume\path.

For instance on a Novell LAN I used to use "truename Y:dsz.com" would
have given \\WSC_PDX1\USER1\PUBLIC\BIN\DSZ.COM which translates as
Server: WSC_PDX1
Volume: User1
Path: \PUBLIC\BIN\
File: DSZ.COM

Try it on something that's been re-assigned via SUBST or ASSIGN or JOIN.
It'll report the *real* path.
