Yes thetahsk that was also my fist and easy step. The point is that I want to test if there is, and if so, to use or create a sub directory on a SDcard. Therefore I need sure about the correct name in the second string option in the object. Your solution gives the sub directories of the phone memory. Every phone or tablet has a different name for the SDcard.

To access a SDCard or USB Disc you need to use the ExternalStorage Class. At least on Android 5+

I search the forum for two days, bud I can't find the answer

Click to expand...

1/ I'm hoping that "two days" is overstatement for effect

2/ Another useful place to get information is within the IDE itself, which tells us that GetAllSafeDirsExternal returns a String Array (which cast reasonably well to Lists, per Manfred's prompt answer):

Yes there is so much information on this site. I read a lot in those two days. In addition to studying the instructional videos, I have also read many interesting things that are often casually reported in answering questions from forum users. And I probably would never have read it if I had written an object "out-of-the-blue" in one go to a list . Thanks to everyone for the help offered .
