How to change permissions in Public Folder?

I’ve been trying to add content to the Public folder but all the subfolders (e.x. Shared Music) Are read only and every time i try to change it it resets it back to read only. I can drag and drop just fine but i’ve been trying to move large ammounts of content so i’ve been trying to use robocopy and it keeps denying access. Is there any way i can get around this limitation. I’ve been trying to not use the wd backup program. 


on my Win8 are new folders in \ \ public, all read-only. But the files are created without write protection.

Under the Windows Explorer can also be seen that there is no clear write protection. This is a short write-protection version with the Linxs translation.
