To use Zaxo's solution and get file size you may do something like this. `#!/usr/bin/perl use strict; use warnings; my $dir = '/path'; my @names = map {[$_, -s]} glob "$dir/*"; for (@names) { printf "%-10s%s\n", reverse @$_; }` [download] The -s function gives the size of the file. See perldoc perlfunc. The explanation of -s and other file test operators is given near the beginning of the docs here. Hope this helps. Chris	[reply] [d/l]

This one only returns files, excluding directories. It doesn't pull in the size of the file, but depending on where you need it, you can get that using the -s file test operator. `#!/usr/bin/perl use strict; use warnings; my $dir = 'c:\\temp'; opendir(DIRHANDLE, $dir) or warn "Could not open directory $dir.\n"; my @dirs = grep (!/^\.\.?$/ && -f "$dir/$_", readdir(DIRHANDLE)); foreach (@dirs) { print "$_\n"; }` [download]	[reply] [d/l]
