I assume you have the "many files" stored on your C: drive and you want to put them on a server? If so, then just copy and paste them into the correct folder. Whenever you try to access any of the .idw's, .iam's, and .ipn's you'll have to direct the program to the new location(s) of the respective model(s).
Need a little more detail on what exactly you're trying to do.
