I have a certain wav audio file. When I transfer it through FTP to my server, it stops at 1%, and the FTP client timeouts, etc. It WILL NOT copy.

If I grab a different wav file, it copies fine. It seems to be only with audio files made with a certain audio program that don't FTP.

Then, I tried this: I took a file that I know to FTP fine, and I stuck the "bad" file to the end of it. So, it was 2 files in 1.

When the FTP got to 50%, it stopped.

It is like it is hitting a certain string in the file causing it to stop.

I have tried multiple clients, I have tried switching between ProFTP and PureFTP. Nothing works for these particular files!

Any thoughts here? Please help!!!

That sounds like the correct diagnosis. Maybe something's wrong with the program that creates these .wav files. Maybe the program's saving them in a corrupt form somehow.

Even if they were corupt, why would it matter? FTP should not know or even care if those files are text, audio, or random garbage. Shouldn't it just transfer whatever is there?

It should. Is the file sitting on a bad sector of your drive? Can you copy the file locally?

I can make a copy of the file, and rename it, move it to a new directory... it still won't copy.

I can append it on to the end of another file, and it still won't copy (it stops at 50% when it reaches the end of the other file and starts this one)

It's crazy!

Have you tried uploading using another FTP client? Verify the client is sending files in binary, not ascii.
