Can't find uploaded files

[Geoff Shang]

Hi,

This one has me *really* stumped.

A user uploaded some files via FTP to a server running ProFTPd.  Now if 
one logs into the FTP server, one can see the files that have been 
uploaded.  But nothing else can.  I can't see them at the shell and I also 
tried writing a PHP code fragment to list the directory and it can't see 
them either.

The FTP server listings even survived a restart of ProFTPd.

Any thoughts?  Are these files really there or not?

Geoff.
