in reply to How to get full path name in windows?

Am adding just a "kobo" suggestion, using your OP and the modification provided by ww to your script.

Anonymous Monk says:
"..D:\Prog\Perls is the location where I execute my code.."

In that case, you can get your desired result using chdir. {Updated}
Like so:

#!/usr/bin/perl use warnings; use strict; use File::Spec; my $dirname = "C:\\Users\\Me\\Desktop\\Cluster1"; my @file_to_use_later; ## for use later chdir $dirname; ## add this to OP script opendir DIR, $dirname or die "can't open directory: $!"; my @FILES = readdir(DIR); foreach my $FILE (@FILES) { my $fil_path = File::Spec->rel2abs($FILE); print "File path:", $fil_path, $/; push @file_to_use_later, $fil_path if -f $fil_path; ## check fi +les contents later } closedir DIR or die "can't close directory: $!"; ## test the files stored in the array variable later for my $filename (@file_to_use_later) { print $filename, $/; open my $fh, '<', $filename or die "can't open: $!"; while (<$fh>) { chomp; print $_, $/; } close $fh or die "can't close file:$!"; }

Also, take note of this important info from File::Spec documentation about the "rel2abs".
rel2abs() Converts a relative path to an absolute path.
$abs_path = File::Spec->rel2abs( $path ) ; $abs_path = File::Spec->rel2abs( $path, $base ) ;
If $base is not present or '', then Cwd is used. If $base is relative, then it is converted to absolute form using rel2abs(). This means that it is taken to be relative to Cwd.

On systems with the concept of volume, if $path and $base appear to be on two different volumes, we will not attempt to resolve the two paths, and we will instead simply return $path .

The above explain, why you are getting this:
D:\Prog\Perls\doc.txt D:\Prog\Perls\volt.txt D:\Prog\Perls\holiday.txt
instead of this
C:\Users\Me\Desktop\Cluster1\doc.txt C:\Users\Me\Desktop\Cluster1\volt.txt C:\Users\Me\Desktop\Cluster1\holiday.txt
Update:
You may also want to look into the module Path::Class and it's "cousins".
Path::Class 'just' is a "wrapper" for File::Spec.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

[choroba]: that's 2012
[zentara]: I just acquired a computer with the card type, and wondered if it was best to stick with the open-source code or use NVIDIA's proprietary code
[zentara]: do you feel good about a non-open-source code, being in control of your display functions?
[choroba]: If you're not going to play 3d games on it, using the open source driver should be enough
[zentara]: choroba that is true, and the wise choice, but I want to see how fast I can get fglrx3dspheres to run... just as an intellectual challenge :-)
