    When I was using,
    opendir DIR, $dir;
my @file = grep { $_ ne '.' && $_ ne '..' } readdir DIR;
closedir DIR;

    to list all files in the directory, opening those files with, 
    foreach $file (@file){
    open(MYFILE, $dir.$file[$i]) or die qq(Cannot open $file[$i]\n);
....some other stuff

    would work. But now using the glob, it's dying when open the files in the files list.

         Well, in addition to the previous comment about the directory path (which is correct), this snippet would not do what you want because you aren't setting $i; you are using the scalar $file as an iterator variable, which is being set to successive elements of array @file, but then in the loop you are always using the "$i'th" element of @file, and you don't show any indication that this (totally unnecessary) array index counter is being set or incremented.

        On top of that, your error report is misleading: you try to open a file called  $dir.$file[$i] and when that fails, you only report trying to open  $file[$i], so you would never know when the problem is due to the content of $dir.
