The File::Find and related solutions provided are the best answers to getting the task done.

However, so you understand the mechanics of directory recursion, as well as a bit of codestyle cleanup, I went ahead and modified your snippet to do what you ask without File::Find.

Update: Moved the report file open/close to the main function and corrected one of the comments.

Examine at your leisure:

#!/usr/bin/perl

use strict;

my $DIRSEP = '\\';    # FIXME  This is for DOS/Windows.  Make this mor
+e portable.


open(OUT, '>fileout.txt') or die "Couldn't open the " .
    "fileout.txt file for writing.\n";
&CheckFileAccess('.');
close(OUT);

exit;


sub CheckFileAccess() {
    my $BaseDir = $_[0];
    opendir(HERE, $BaseDir);
    my @AllFiles = readdir(HERE);
    closedir(HERE);

    # Pass 1 for files, Pass 2 for directory recursion
    for (my $curpas = 0; $curpas < 2; $curpas++) {
        foreach my $Name (@AllFiles) {
            my $RelName = $BaseDir . $DIRSEP . $Name;
            if (!$curpas) {
                # Process Files only; if directory skip to next filena
+me
                if(-d $RelName) { next }
                my $FileAcc = sprintf('%3d', -A $RelName);
                # Check for files that have been accessed in the last 
+10 days
                if ($FileAcc <= 10) {
                    print "$RelName ";
                    print "File was last Accessed ", $FileAcc, " days 
+ago\n";
                    # ------------------------------------------------
+---------
                    # DANGER  printf could have produced interesting a
+nd
                    # unexpected results here, so I changed it to prin
+t.
                    # ------------------------------------------------
+---------
                    # printf OUT $Name . "\n";
                    print OUT $RelName . "\n";
                } else {
                    print $RelName, " File was Accessed more than 10 d
+ays ago\n";
                }
            } else {
                # Process Directories only
                if(-d $RelName) {
                    # Skip danger directories
                    if ($Name eq '.')    { next }
                    if ($Name eq '..')    { next }
                    # Good to go -- prepare for recursive call
                    &CheckFileAccess($RelName);
                }
            }
        }
    }
