Is it possible to allow uploading all file types and extensions without modifying the code of LS core?

(And yes, I know that .js, .exe etc. might be Bad Thing(tm).)

Have you tried something like *.* or *?
I don't expect that to work, but it would be the only way I would try to solve that issue.

If that didn't work, you will need a change in the codebase or a feature request.

*, .* and *.* did not work. I'll make a feature request.

I was not even able to find the right place in the code to override this restriction. Should I modify some file under iiwheels-directory?
