Trying to join a bunch of small wmv's into a big one. Thought the script was: @echo off copy /b file1.wmv + file2.wmv "combined.wmv" @echo All this gives me is a large file with only the video from the first file. I also tried using a *.wmv that gave me the same results and if I leave off the /b it doesn't work at all. I know this works but I just can't remember what I'm missing. Any ideas?
