>Problem is that a shortcut built into the VFP program to call another program uses SYS(5)&FOLDER2\FILENAME. The program runs, but a data file the program is dependent on is not found. When the VFP program is run from the desktop shortcut, the data file in the second program is opened successfully. Why does sys(5) return different values?

As documented sys(5) return default drive not the drive where exe reside. If it's called from an appliacation that uses \\XPbox\c as working dir it'd return \\XPBox\c. Invoking from its own shortcut returns c: because its shortcut has a 'Start in' folder somewhere along c:. To get exe's drive use :
justdrive(sys(16))
or :
justdrive(Application.ServerName)
