not sure I fully understand, but I'll have a stab anyhow.
you need to elaborate a little,
are the machines on the same network ?
are they both configured to allow shared files ?
anyhow, you can quickly try to map a drive within windows. which is outside of the programs control.
you can do this from the search box at the bottom of the start menu, just type;
net use * \\{pc name or ip address}\sharedfoldername
so for example on my machine here it would look like this; net use * \\ant-7pc\public
this would "map" a drive which you should be able to reference in the config of your program.
let use know how you get on.
ant
