>I just came back from the customer site where they are using the app via Citrix. I wish I knew to go to Windows Explorer to look for the server drive. I thought that WE will only show me the local drives of the PC. Next time I will try it.

It's the other way around: in a Citrix session, you're looking at the server. The c: drive you see there is actually a mapped directory given to you by Citrix, i.e. there's one such directory per user. Now your Citrix client may (or may not, depending on security settings) map your local drives - which are actually remote drives for the duration of the session. Literally, you're sitting on the server, and whatever you see there is from the server's POV - and if you see yourself (your drives, that is), it's from afar. You'll notice that by the speed of copying.
