cocoa - How to determine a volume supports resolving bookmarks to renamed or moved files? -

-

- bookmarkdatawithoptions:includingresourcevaluesforkeys:relativetourl:error:

documentation states:

this method returns bookmark data can later resolved url object file if user moves or renames (if volume format on file resides supports doing so).

from trial , error seems (internal?) hard drives support it, looking kind of sure test nsurlvolumesupports???key.

nsurlvolumesupportspersistentidskey looks candidate, failed find docs or google-info it. hints?
