I selected to keep the file after install hoping I could pull the files off and save them to an external but have found it quite difficult. The files ONLY show up when my switch is connected via USB and tinfoil is running. Any attempt I try to copy/delete/modify any of the files while its connected revert as soon as I close tinfoil and restart the app. The files are right back where they were and I am unable to copy them. When I drag a file to copy it gets stuck and copies nothing. I have tried going into the install setting of a game and switching it to delete after install and tried re-installing the game but the NSP file still remains. If I delete the game and redownload it and select to delete the file after install then the file finally erases. Can anyone explain how to pull these files off so I don't have to re-download every single game all over?
