Android Question Can I save data to a specific folder on my own tablet?

Can I save data to a specific folder on my own tablet? And if so, how to do it?

Well, for example,
/storage/emulated/0/Download.

The fact is that I always develop my programs only for myself. And I know for sure that there is such a folder on my tablet.

If I understand correctly, all these

File.DirInternal / File.DirInternalCache
File.DirRootExternal
File.DirDefaultExternal

are intended for those programs that we give to someone and we do not know in advance what folders they have on the device.

I tried this File.DirInternal and I didn't like that using the file manager it is impossible to find the saved files.
And for some reason File.DirRootExternal doesn't work at all. Maybe Root rights are needed for this?

Here are some examples:

SaveAs - Let the user select a target folder + list of other related methods

Manage External Storage - access internal external storage >= SDK 30

Google seems intent on dumbing down Android to the point of uselessnes to me. I think of my devices as little computers and I want a proper file system on them, not the limited tortuous things that Google offers and that I don't understand, ContentChooser, FileProvider, ... o_O I'm getting old...

Since its your own tablet, you can change the TargetSdK in the manifest to 19, then you can easily create the folders.

This will not work with Android 14. You can however set the targetSdkVersion to 29 and the "request legacy something": https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/#content
