如题

Hello, I saw your post on SegmentFault, and have "parse-torrent" package and "MD5" package installed. However, the scripts did not run well.

Error messages are as follows:

/Users/changmin/GitHub/Clean-Torrents/cleanTorrent.js:30
for (var i = 0; i < files.length; i++) {
^
TypeError: Cannot read property 'length' of undefined

Is there anything wrong with my operation? Many thanks for your help.
