Working with large data files (hundreds of megas)

I am trying to figure out the best way to to work with huge data files. For
example, I have a compressed (gzip) file that is 13 mega and when I
uncompress it it inflates to abut 90 mega and i have several of these.
I would like to know if there is a way to work with compressed files within
mathematica either 2.2 on a unix platform or 3.0.1 on a windows nt 4.0. my
nt is hooked up to the network so i have acces to the unix drive where my
file is located. I would like to read the data from the compressed file and
perform my analysis and write my results into a compressed file to avoid
giving my sytem administrator a fit as I would use up all the disk space
space quite fast working with the uncompressed files.

thanks a lot
