nsyed,
I have never used Net:FTP::Common, but from the docs:

$ez->dir (%override)

When given no arguments, dir() uses Common configuration information t
+o login to the ftp site, change directory and transfer type and then 
+return a hash of with detailed description of directory contents. You
+ may only call this routine and expect a hash back.

my %retval = $ez->dir;
[download]

The hash will have keys like owner, size, etc that you can use to get the information you want

Cheers - L~R
