Hey guys. I was looking to clear up some things in my SD card, I have already made a backup on my computer. There is this 1.47 GB file called "private". It contains folders of SZDE SZAE sZCE and SZBE. And then in those are .bin files with numbers? I am also looking to make a backup of my nand from bootmii, so how big of a file will that be? Thanks for your help.
