@patel

Can I list a subdir (Documents) created with filemanager in the asd of my application ?

Yes, but how about just trying this out for yourself before asking any questions here.
(Only two simple blocks are needed for this.)

I have 2 buttons with text Documents and Download an 2 subfolders as above.
Attached my blocks

Thank you, if I understand well my mistake is having created the subdir with filemanager

[Anke]

@patel

if I understand well my mistake is having created the subdir with filemanager

This shouldn't make a difference.

[patel]

I tried with these blocks, the documents folder was created, then i copied in that folder my documents, but the app does not run.
