Yup. The default glob() function s based on the C-shell and spaces are
separators. If your file names have spaces, use the BSD glob. This will
replace glob() with one that allows spaces in the file names.
use File::Glob qw( :bsd_glob );

Re: reading directories using perl in windows
FYI, there is no error. If the directory
path has no spaces it works fine, if the directory
path has spaces it prints the path up to the 1st space
and just goes back to a cursor line.

Could you please send the exact error which you are getting as I
Copy/Pasted the exact code which you had given and it is working
properly for me. I have only given the directory which is present in
my system.
use strict;
use warnings;
my $dir = "C:/Python_Exercise/*";
my @files = glob( $dir );
foreach (@files ){
print $_ . "\n";
}
