In order for me to read my comics on my PSP i need to convert them into jpg format. The official format of my comics is cbz, and i cant convert online because all the comics are about 7 gigabytes.

Assuming your file name is sample.cbz, just:

7z x sample.cbz -osample

image files would be extracted into sample directory.

where is the "sample" directory? do you mean it will extract the image into the same directory as the cbz? – Nick Bailuc Jun 29 '12 at 2:19
Yes, the -o option sets the output directory. see 7z(1). – Mohammad Jun 29 '12 at 2:30
thanks, that helped – Nick Bailuc Jun 29 '12 at 2:59

.cbz files are actually a zip file with jpgs or pngs in it.

Change the file extension from cbz to zip, uncompress the file with Archive Manager, then you'll be shown a bunch of image files!

there are 7 gigabytes worth of files, it will take forever to rename each, but thanks ill consider the fact that cbz is a compressed archive – Nick Bailuc Jun 29 '12 at 2:17
