When using the CallbackFS to host a drive we are having an issue where the system requests to create a file called 'thumbs.db:encryptable' which I understand is an alternate datastream object but I was under the impression that alternate datastreams should not be forwarded by the driver, is this correct? If not, how should these datastreams be dealt with?

Description:

After creating an Image in an empty folder and switching to thumbnail view, CbFsCreateFile is called for the file ‘Thumbs.db:encryptable’

It's our mistake. Sorry. If you don't set a pointer to the CbFsEnumerateNamedStreamsEvent then the alternate data streams must be processed internally by the driver (it simply completes such request with STATUS_NOT_IMPLEMENTED). But there is a problem here. In the following build it will be fixed. Now for such requests (i.e. for Create('thumbs.db:encryptable') etc.) you can return the ERROR_NOT_IMPLEMENTED error.
