[HD2 Android Q&A, Help & Troubleshooting and Genera] HypoTurtle:
Had a though about how 7z etc. does stuff (on windows)- when you open a zip and alter the files without extracting it (essentially a tmp folder is created) so tried to trim down on the altering of the zips. (just in case that's what's eating up the memory - zips extracted to RAM).
