Ok so this is going to be a level 0 noob question so bear with me. If I used comtype scanner to confirm the correct algorithm, and the file is just compressed data, and I don't care for names. How can I create a quickbms script to simply unpack it like comtype scanner does, so I don't have to go through the scanner to unpack it? I'm also curious, is it documented on here already and have my google skills let me down? any help will be appreciated

There are some wrong things in your question.

You mention "just compressed data" and then immidiately say "don't care for names", that's not what the comtype scanner is meant for since it looks like your input is a whole archive and not a raw compressed data.

The comtype scanner is a powerful tool for reverse engineers: you have a file containing 100% of unknown raw compressed data, you also know the decompressed size of that data and you want to know what algorithm has been used to produce it.
Then look at the results with a hex editor and check what of them contain the expected data.

So if you need a script just ask on the forum
