My psychic powers tell me you are doing this through CGI and the anonymous user "httpd" or "nobody" or "iusr_xxx" does not have permission to write to the directory in question.

Second, what's with all the backslashes? Yech!

Third, You should use the rename function within perl (or the File::Copy module) to do your moving, not an external command.

Fourth, you should use Archive::Tar to handle your extraction, not an external command.

Fifth, whether you use modules or external commands to do your file handling and extraction, you should always, *always*, ALWAYS return the error message from the operation ($! for perl system functions, $? for system commands.
