Now that code tags have been added to your node so that the code is clear, the problem also is clear. You are using [] in the regex which means match any of the characters within the square brackets. The fix is almost easy - use a non-capture group ((?:...)):

if ($filename =~ /(\.(?:htm|html|txt|pdf|ppt|csv|doc]))\b/i)

Note that the repeat ({3,4}) is not needed.
