Whenever you see code with File.DirRootExternal you immediately know that it is wrong.

You cannot directly access those folders.

The various options are listed here: SaveAs - Let the user select a target folder + list of other related methods

Thanks for reply, pardon me for my dummy questions,I'm newbie
do we cannot make folder of course getting permission by file.makeDir on user phone any more?
Is the user have to chose the path for each download Every time?
If yes, Is there a way for a simple app to get user permission just once to use the download directory all the times?

True. You can't unless you are using File.DirInternal=XUI.DefaultFolder.
The read/write external storage permissions are no longer relevant.

Is the user have to chose the path for each download Every time?

You can use ExternalStorage to get a more persistent permission, but it is a bit more complicated.
