Re^2: How to delete empty files

HI
your example gave me an error message

Use of uninitialized value in string eq at C:/Perl/site/lib/File/Find/
+Rule.pm line 586.
Use of uninitialized value in substitution (s///) at C:/Perl/site/lib/

It seems that what gave you an error message was "C:/Perl/lib/File/Find.pm line 593", to be more precise 'invalid top directory'.

What is your directory argument? Are you leaving it at $ENV{HOME} ? Is this environment variable even set on a windows system?

Add this to the first lines of code, before we instance File::Find::Rule..

defined $ENV{HOME} 
  or die("ENV HOME is not defined.");

print STDERR " # env home is set at $ENV{HOME}\n";

-d $ENV{HOME} 
  or die("ENV HOME is not a directory");

(You can always bite the bullet and switch to linux. It takes about a year to get comfortable, if you're considering.)

Furthermore, *DONT RUN THAT SCRIPT*, it's just an example script! :-)

Substitute $ENV{HOME} with something like 'C:\path\to\where\you\suspect\empty\files\reside'.

And *read* File::Find::Rule!

Don't give up so easily- if something does not work, that's when you start 'debugging'. Takes up most of my time, between tests (.t) and errors, and the fact that a third of my code is to check and recheck return values and results.. In the long run it's saved me a lot of sweat and blood.
