I've never had to use a command line script before. I have been using JoomlaPack to backup my site. I had a db file corruption and when I tried to reinstall a backup the only one that would work was 11 days old.
I was able to get most of the data back bc I SQL'd the db before the reinstall. But I need to get some of the files, like people's profile picture and such, out of the .jpa file. Apparently the only way to do it is with your command-line script.
Your instructions say to use it by command-line but not what that is or how to use it.
Please point me to these instructions. I've spent over 24hr trying to figure this out on my own. It really should be easier for someone new to this to get this information.
