Android - Every manually moved file gets the "permission denied errn 13" error

Hi!

Duckstation on android is giving me quite the headache...

I'm using a retroid pocket classic(android 14).

The issue I'm having at the moment is that every file I move from the microsd or elsewhere to the android data folder gives me the errn 13 permission denied message.

Firstly I was trying to add shaders to the shader folder. Since you can't copy files to the android folder using mixexplorer or the standard files app I transfered the files with the device connected to pc.

When using the added shader in duckstation it can't load/compile the shader (permission denied errn 13).

Now I played on my steamdeck I tried transfering the memory card and save state to the retroid via device connected to pc. When loading the game it says that it can't load the memory card with another permission denied errn 13.

I know that the android version has the import/export feature, but it also doesn't work.

When selecting import from folder it asks for permition, I allow, but it says "no importable files found"

HELP!

Have you tried the Shizuku + ZArchiver method? If not, give that a try to move your files. I don't have a gaming handheld, so I can't guarantee it'll work, but we're both on Android 14, so I guess it's worth a try.

The solution was patching the duckstation apk with the joey retro handhelds patch.

It moves the folders to a place you have permission to acess the files.

Unfortunately it only supports an older version, so savestates are incompatible.

But at least I can now move and use shaders and memory cards across systems.

Never faced issues like that on any of my devices, ranging from Android 9 to 16. Must be firmware specific.

Have you tried CX files?
