Joiner for Linux

[Manuel Gomez]

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.
