6.55 MBs from just text files? Is this compressed or not compressed? Make sure to use a non-WinZip or XP archive utility, such as
WinRar, to get good compression rates (make sure to use Best). In fact, going with a format such as RAR will give even better results. You can add a mere 50 kB SFX (self-extracting) module to an archive that will allow it to be extracted without having WinRar installed. 50 kB is nothing when you can sometimes save 5 MBs in RAR format vs. ZIP format (and this is with Best compression in WinRar of each format).
