Hi Casey,
There are a couple approaches you can use.
On startup read a setting from a "known" location. This determines where the data is. You could use an INI file for this, or a registry entry, or whatever you prefer.
Then do one, or more, of the following;
a) use SETPATH to set the current folder to that location.
b) use System{prop:datapath} to set the default data file location to that folder or
c) use individual file names to set the location of each file.
Remember though, that a service may not have access to the network, so be cautious about putting service data files on a network drive.
Cheers
Bruce
