Erel B4X founder Staff member Licensed User Longtime User Aug 15, 2019 #2 Google documentation: https://developer.android.com/reference/android/support/v4/provider/DocumentFile A single document may appear as the child of multiple directories, so it doesn't inherently know who its parent is. That is, documents don't have a strong notion of path. You can easily traverse a tree of documents from parent to child, but not from child to parent. And see this: https://developer.android.com/refer...v4/provider/DocumentFile.html#getParentFile() The external storage does include a "parent" feature that is based on the stack of folders. You can do something similar in your app. If you are looking for a way to get the parent folder of the folder the user chose then it is not possible. Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Aug 15, 2019 #4 There is no such thing. You only get a uri (stored in Root) and you can get the files and folders in that root folder. The uri might include and might not include the actual path of the file system. Last edited: Aug 15, 2019 Upvote 0
