How to Transfer Apps to USB Flash Drive.

Wait 5 sec.

Hello.I have an S23,Android 14.I'm trying to move some Game Apps that I installed onto a USB Flash Drive.No matter which USB Flash Drive I use.I always get the same Error Message:Not Enough Storage Space.I even enabled Force Allow Apps on External in the Developer Options.It just won't work.Does it not work with a USB Flash Drive?Does it only work with Micro SD Cards?Any help would be appreciated.
