I have 1300 excel files on a server, with revenues in them. I need to compare these revenues with one pivot file to make sure the revenues are the same in the actual 2 files. Because it is on a server, opening all of them from a server would be pretty slow, thats why I want to copy a sample of them (25 excel files) to my compter first, and then run my comparison macro from this folder. But I want to make the copying process automatized, so I somehow need to select randomly 25 of these files, and then copy it to an other folder. I have a code to copy all of the files from one folder to another, but I need the random selection to it. Thanks.
