While the file may appear in the directory, it may not have any data or that 
may be incomplete. Also, IIRC setting "faststart" occurs when the file is 
being closed, so you'll have to wait for that and for the file system to 
flush all of it's buffers.

This also depends on which OS, which file system, storage media, etc.
