its no issue on Windows, both commands can have its uses. So here its no problemo to uses the both.
To make more seance on Android "DOCUMENT" should changee to uses sdcard external data dir (if that exists), not on the download folder. If that data dir doesnt exists, its might returns same as the "APPDATA". This is all Java thing.
DOESFILEEXIST act nearly as before and also still act normall with "APPDATA". From Media folder, its also copy the requested file from APK to the internal memory on the fly, before its checks the file exists.
That is required on Android, because glbasic cannot read directly from the APK file. So before all Media files was installed to the internal memory, that was done by the "..." waiting screen. That screen is now skipped (as its was done in nearly from AE beginning), but its need to copy the files from APK somewhere.
Here DOESFILEEXISTS and DOESDIREXIST do that job best. Its actuelly what its does practically for you. Later that should also been integrate and doing that automatic for all commands, but im diddent do that for now.
You can eventuelly delete the file when the file have been used from the internal memory again (if low in memory).
Mightbeen that help should been explained better? what should im change?
