I need a file compresser utility that can pack more than 4 million HTML files (totaling a bit over 40GB), into a single 4.5GB archive. Ideally, this archive will be able to be accessed (and a single file pulled out), without loading the entire archive. The archive file will be created on a 3.2 GHz Intel Celeron machine, with 512MB of RAM. Is this possible? What file compression utility should I use?
