Folders

Have also tried:

Dim slm = dbx.Files.GetMetadataAsync((filePath))
                    MsgBox(slm.Result.ParentSharedFolderId)

Returns nothing

Apologies, I believe I misread your code.

The SharedFolderId field is only available on folders that are shared. I see that you were actually calling GetMetadata (as far as I can tell, from the variable names you're using), so that won't be available. You should call that on the folder itself to get that instead. I.e., to get a FolderMetadata object.

If you call GetMetadata for a file, you will get a FileMetadata object. If the file is in a shared folder, you can get the parent shared folder ID, i.e., the shared folder ID for the shared folder the file is contained in, from FileSharingInfo.ParentSharedFolderId in FileMetadata.SharingInfo.

And that's correct, if the folder is not yet shared, it won't have a shared folder ID. You should call ShareFolder as discussed earlier to share a folder.

Still not sure what to do here, I have searched the forum, googled it, but cant find any examples of useage anywhere?

Do you have an example of sharing a folder - Event if its in c#, I can convert it.  The function exmaple seems to do nothing.

    Public Function ShareFolderAsync(
    path As String,
    Optional aclUpdatePolicy As AclUpdatePolicy = Nothing,
    Optional forceAsync As Boolean = False,
    Optional memberPolicy As MemberPolicy = Nothing,
    Optional sharedLinkPolicy As SharedLinkPolicy = Nothing,
    Optional viewerInfoPolicy As ViewerInfoPolicy = Nothing,
    Optional actions As IEnumerable(Of FolderAction) = Nothing,
    Optional linkSettings As LinkSettings = Nothing
) As Task(Of ShareFolderLaunch)

    End Function

  ShareFolderAsync(filePath, Nothing, True, Nothing, Nothing, Nothing, Nothing, Nothing) - Folder doesn't get shared.

got it with

 dbx.Sharing.ShareFolderAsync(filePath)

all working now
