I was informed by the manufacturer (MF Digital) that the import 4 is specific for the way Sooloos imports FLAC files. It is not usable for other systems or formats. There are other units that rip FLAC (as well as MP3, apple lossless, etc) files to hard disc and those are then transferrable to Sooloos as well as any other music programs, servers or NAS. I have used the MF Digital Ripstation for this purpose and have about 3 thousand CD's ripped and ready to transfer. However, it is a 2 stage import process. I do find that files are imported into Sooloos a lot faster than ripping CD's. Attached is a link to their site.
