Best method to copy a multitude of files to a folder?

[Windows Network Environment] I need to copy 140,000 files from many sub folders on a server to a common folder (on the server or a different server) so I can burn to DVD(s).

All these files are within one folder directory and in various sub folders. Mixed in with these files are files that I do not want to copy. I was able to get the exact file path for each of these documents. I created a batch file with the copy statements for each file and am having them copied from one server onto another. The batch file is being run from the desktop machine in my office. The process is taking very long, and I was wondering if I was doing this the most efficient way.

How could I adjust the method to be more efficient? Copy the files to a different folder on the same machine? Run the batch file from the server with the files on it? Use a different method than a batch file?

I’ve already figured out that I could have split the batch file into multiple and run it from multiple computers, but I don’t want to interrupt the process after it’s been running for so long.
