Topic: Concatenating files with DOS "COPY" command

[boojum]

The DOS copy statement allows concatenation of files, "copy filea+fileb+filec file_out".  I am trying to copy some WMV files into one big file but it is not working.  What have I missed?

That will concatenates files the files, not the content of encoding envelopes.

If you concatenate two wav files you will get a file with a wav header at the beginning and another wave header somewhere in the middle.   The first header will indicate a data chunk size of the original wave 1.  When you play back, either the player will stop at the end of the first specified data chunk or it will play through with noise where the second header is.  Or the player may reject the file because the header indicates a size that differs from the size of the file in it's directory entry.

You need a sound editing program.

There are definitely freeware apps that will allow you to do this.  It's been a long time since I've done so, but the apps are out there.  Give Google a go, I'm sure you'll find something.

Solved the problem with WXP's bundled Move Maker.   Thanks for the help.
