Windows 7 Move Command in Batch Files

Which files are you trying to copy and where are the locations from which your are trying to read and to which you are trying to write?

The files are on my flash drive, and I'm trying to copy them directly to the desktop. All of the computers use user names like 734 or 722, so i've tried using wildcards ? and * but neither work

Are you saying that you're trying to specify a user folder name with a wildcard in it, such as C:\users\7??\desktop\*.*

Ok, ill give an example one of the files I'm trying to get the command to copy is example.jar. I need example.jar copied from the flash drive (lets just use letter J) J:\ to C:\Users\7??\Desktop. I'm using wildcards as a representation, each different lab of computers has a different username some are 733 some are 718. So you get on the computer in one lab and everyones' username is 733 where in another lab everyones name is 718. I need this command to be able to run on all of the computers.

You need a different command structure to use wildcards in folders and directories. I'm up to my neck in things at the moment - I'll get back to you asap.

Ok, I appreciate any help you can offer, whenever you have the time.
