It could be a text document or a pdf. file someone wanted to attach perhaps.

This little thing pops up when you use the browse bar to find the "attachment" (file of any type within limits) stating: no bigger than 100000 bytes please uuuhh, is that like the same as 100k?

Does that help? Some files cannot be inserted in the UBB code offered URL, E-mail, Image, and Quote functions I guess.
