XXCopy

Command line pros will revel in all the switches and options XXCopy gives for copying and moving files. Want to copy all the files in a directory under a certain file size? You can do it. How about copying only files on or after a certain date? Sure, you can do that as well. You can do all that, and plenty more, because there are more than 160 switches available to you. In fact, if you're willing to put in the time to learn it, you can use this program to back up files and folders, not just copy them.

Note: If you use XXCopy with Windows Vista, you'll have to run the command line as an administrator.
