1. When I say MM format what I mean is the folder / file organisation method used by MM as opposed top iTunes.
I've looked but can't see any definitive guide to how to import all the iTunes stuff into MM.
I'd envisage allowing MM to manage the media files, with it moving all the actual files into directories as it should.
There is no MM folder / file organization (nor is there one that is actually required for iTunes). The Add/rescan feature will add files from the source you specify whatever its organization (as will iTunes for that matter). And the Auto-organize feature will allow you to re-organize files to whatever organization you want, but you have to specify that. Bottom line, there is no need to change your file organization to use MM and MM won't change it unless you tell it to.
To add files to MM use the Add/rescan feature under the File menu. Find the highest level folder that includes your music (on my system it would be C:/Users/User/Music/iTunes, if I were using iTunes), click on the box next to this folder to get a check mark there and then press okay. Depending on the size of your collection, you could go have a snack or just twiddle your thumbs for a bit. You can then find your music under Music in the media tree (left column). If you have several top level folders with music (I have seperate top level folders for classical and for other) you can check both.
The only time file / folder organization matters is if you use Auto-tag from filename; but again, if the filename is okay in iTunes it will be okay in MM.
You will find, however, that there is data about your files that is not stored in file tags and so cannot be read by MM (or any other player). For example, iTunes does not store track and album ratings in a file tag, but in the iTunes database. And thanks to Apple not playing well with others that information cannot be read by other programs. And due to some limitations of the standard ID3 tag system there may be other pieces of information that are not in file tags but in the iTunes database (and so inaccessible to other programs).
The iTunes drivers are necessary to sync to iPods, but it is not necessary to have all of iTunes installed as explained here: https://www.copytrans.net/support/insta ... ng-itunes/
. That said, iTunes store may be a source you use for which you will, of course, need iTunes installed somewhere.
Frankly, I don't use the MM ripper as I think I get better tagging control using dbpoweramp's ripper, but I have almost exclusively classical albums and dbpoweramp provides tags from SonataDB which is much better than freedb. I know a number of MM power users prefer Exact Audio Copy (which is free). A real advantage of MM over iTunes is that it will play FLAC files (to me this is a much better reason to use MM than "I hate Apple") and will automatically convert them to MP3 when syncing to devices that only accept MP3 files.
