Hi again, I'm still having trouble reading PC formated disks. The suggestion of Bart Lateur fixes one problem, but not all. I still get error #002 when I run the following script as a droplet: #!/usr/bin/perl -w $folder_name = "@ARGV"; $folder_name =~ s/:^//; print "$folder_name\n"; opendir(FOLDER,$folder_name) || die "Could not open $folder_name: $!"; @allfiles = readdir(FOLDER); foreach $file (@allfiles){ print "$file\n"; } Thank You for any help you can give me.
