There are several child folders in parent folder on windows 8.
Times ago I shared some child folders and accessed them from android es explorer without problems. Then I removed all child folders shares and instead shared their parent folder.
During the parent folder sharing the window appeared listing some of the previous child shares and asking "some of the folders were previously shared. you can replace their current settings with the same setting you just applied to the folder you shared".
If I click change settings after processing for a while it ends up with "folder can not be shared". Despite the message it is shared but access to those children is forbidden, they are not visible.
