I am searching a joiner for Linux. I need to join an document with another archive, and i want can open the document without problems. I am not creating a trojan or something, its for add size to specific documents (security-> If the document have 5 kbs it takes 5 sec download it, but if the document have 500 mb it takes a couple of days, and i turn off the connection constantly. Believe me, for me is usefull). Somebody could help me? Thank you very much.
