Help - Adding size to a document? More security

[Manuel Gomez <mgdpz1@gmail.com>]

Hi, i would like to add more size to a document to avoid hackers. If the
size is too big, troyans won't download the archive (it would take days
and days...)

How could i do this? I am using "SFX compiler" for join an archive (3
gb, for example) with my documents, but i would like to know how its
done.

I need: Open the document (for example, dbs in openoffice) in Linux, and
more than 1 gb of size.

Thank you very much, I appreciate your help.
