Films & Music Videos?? What about television series DVDs or home movie DVDs? I have several category folders for DVD rips but I also manually place them where I want them
I'm constantly amazed at this ongoing struggle. I don't like to be a slave of the file/folder structure. But whatever file/folder structure I had before moving to MC had some solid logic, that allowed for importing the structure as fields in MC. Once that happen I'm less bothered with the folder structure, only just enough to keep it consistent. Then I can just shuffle any kind of hierarchy from within MC, if I really need it.
All my movies have one folder each, directly on the root of the drive. Every series has also only one folder on the drive. Inside the series folder there are no subfolders just episodes with a [Season]x[Episode] - [Name] name scheme. All details captured. Genre and the likes will come in from IMDB and other sources.
Any kind of structure like \Movies\HD\Sci-Fi\Blade-Runner\[finally the movie here] gives me headaches. And it may not be a sound choice in the future. Say something happens in the foreseeable future that you cannot control from within MC (which amazing as it is doesn't deal with a couple of things that the media center general community has much interest in - fanart, multiple screenshots per item, etc). One will be hard press to navigate a complicated folder structure to investigate one thing or another.
Bottom line. You do not need to obey any structure for the sake of being superorganized. First it needs to be practical, now and in the future (which is an aspect I believe we often get distracted from). Then it needs to be as simple as possible. Add granularity if you want with the tools that allows you to do it fast - the database, not with the one that implies a lot of work - the file system.
