Your description of what you're looking to do is a bit vague, but obviously using wildcards in a command line is an option, depending on what the filenames have in common.
Another option is to list the directory into a file and edit the file into a batch file. For XP, get a command window, change to the folder containing the files, and do dir /B > \filelist. Notice I put the target file at the root of the drive so it won't appear in the list. Then use a text editor to fix the list file into the list of commands you need and change the files name to filelist.cmd. Copy the batch file into the folder so you can run it from that folder, or it won't find the files.
At first that sounds like no different than typing the commands, but you can use cut and paste to build the commands, which saves time.
Also, copy the folder somewhere safe in case you mess it up. You can get a fresh start that way if you need to.
