Can't modify flv files

[topper2k]

Here's what's happening:

If I post a new FLV file to my applications directory, I can rename it, post
over it delete it etc. so long as the file has not been streamed to a user
through their browser.

If I access the video stream through my browser, watch the entire video, close
my browser and then try to rename, modify, or delete the FLV, I get the message
"Cannot rename (my file) It is being used by another person or program."

Is this normal behavior or is something wrong? If it's normal how do I manage
my files?

I've tried to look a little closer at this problem and am still not getting
anywhere. Does anyone know if this is normal behavior for the Flash Comm
Server? Is there some way to stop or suspend the streaming process so I can
delete some files?
