I have several folders of around 8GB or so. Together these folders total around 60GB of data. I can compress these folders one of two ways: either individually, creating one compressed archive for each of them, or altogether into a single large compressed archive.
Generally speaking, assuming all the data to be compressed is of the same type and the compression algorithm used is the same (and that I also don't care about the time it would take to decompress the larger file), will either method result in better compression than another, or will the total sizes of the compressed files in the two scenarios tend to be equal?
