Change it to a while loop: 
    while (@files) {
    ...

That should fix your problem, cause it'll only loop as long as there are elements in @files. Whereas yours was actually looping *over* @files, which is a different thing, and not recommended if you're going to be modifying @files (which you did, by using shift).

Alternatively, though, you may want to try using splice: 

    push @data, [ splice @files, 0, $num_cols ]
        while @files;

splice grabs chunks of an array (and can also replace those chunks w/ a list) and increases/decreases the size of the array as necessary. Sounds good for your particular use.
