Yo do not delete anything from your PS4.
To mass install all your previous apptousb games again:
In the ini files (both of them) uncomment CHECK_USB and MOVE_MODE and make a list of the CUSA's you want to move at the bottom of the file.
Move all the app.pkgs from the CUSA folders to the root of the USB drive. (if they are all named app.pkg then rename then to their CUSA name eg CUSA34521.pkg
Do not run apptousb yet but instead use the pkg installer in the debug menu and select install all pkg's
It wil probably say they are already installed so just install them again as you go.
When all the games are installed on the PS4 then run apptousb and it should move all the games in the list to your USB drive.
It will be faster than normal because you uncommented CHECK_USB so it will just move the pkgs from the root of the USB into the CUSA folders on the USB.
