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 gilberto espinoza gespinoza at earthlink.net
