I will post this as a separate thread from the PS4 PKG2USB as the 2 payloads vary and it saves confusion.I was playing around with the ext0 mount and recreating the file structure that would be there if the pkg was installed to external storage.There is a trick I found where if you copy thefolder fromtoand then unplug the hdd and plug it back in it causes the ps4 to do a repair and then the game is recognized as installed on external storage and from there there are other issues.with the great workhas done in PKG2USB with the symlinks its a lot easier to manage with exfat and just normal USB.So building on his PKG2USB and symlinks I modified what I was working on for the ext0 mount to work with the usb0 or usb1 and symlinks.This payload searches the entirefolder and copiesgames to usb from the system drive and creates the symlinks likehas kindly shown us the ability to do.If you want to target a single game not the whole folder use PKG2USB If you install more games just run the payload again and it will copy any new games to the USB and so on.With symlinks you are making a link to a directory so you want to pick which USB port to have the hdd on and keep it on that same port or the links will point to the wrong directory.is what I use.Thanks again toby seanp2500
