I have a dilema that I haven't found in any postings, although I'm getting closer. I have a directory of 15 files or so, and I want to put the .bak extension on all of them, so from us093190.wmv to us098190.wmv.bak, which i figured out how to do. Now, I want to copy just the us098190 and paste it onto another file that I copied from the directory above. So, I have a countdown.wmv file in the directory above, and I copy that file into the current directory, and I want countdown.wmv to be named us098190.wmv. I want to make a batch file to automate this process. Thanks for any help!
