Use one of the File extensions:

Taifun's File Extension
Sunny's FileTools Extension

both found here

how?? can you please explain ????

Have you read the descriptions of how the extensions work and what the various blocks do ?

In essence use the block that returns the specific directory you want to a list, then display that list in a listview/listpicker for file selection

no i do not want this i want when I click on button it redirect my phone download folder.

Use the activity starter

No, because there is no way:

It's not clear for me, can you explain better ?
