File Locked

I have a folder full of video files. my application allows multiple users to watch the video in an embedded quicktime player.

if when the quicktime player is viewing the files and the "content creators" attemps to save over the content (content is on a server) I am unable to delete the old content in order to save the new

"File is in use by another process"

Is there a way to free that file up by closing all remote connections to the file?

You could temporarily copy the file to the local machine prior to viewing it, that way
the original file is not being locked and can be freely overwritten/removed.
