There is an .app.out file you must have from this process, that is the one you must use, besides that, in the next step, which is the unique id of the file, you must put the big number in the xorpad files, the one before the first dot (.)
I didn't get an app.out file :|
I just got a bunch of XORPads.
It says that the .out file is generated after doing the pad process, and I haven't done that because I don't know what the file it wants me to put the name of is
