Hello,
While browsing your website, I noticed that on one of the pages you have a broken link. This is at the
http://www.gnu.org/software/libextractor/ page and the link to
wotsit.org.
I was wondering that maybe you would like to fix this for your future readers and put a link to one of the currently popular file formats databases, e.g.
file-extension.org.
Greetings,
Adam Brankiewicz
