I do the same thing. I spent over 10 years building my music collection and the file/folder structure. I didn't want iTunes messing it up, as it can do quite easily. My convention is:
Genre folder
.....Artist folder
..........Album folder
...............Artist 01 Song Name (where 01 is the track number)
Whether I follow the conventions above depends of different factors, including:
- How "deep" is the data?
- How important is it?
- How many versions are there?
- How dynamic is it? (e.g. Photos, where I shoot 100 to keep just 2)
- Is it "One Off" or part of a "Collection" (e.g. Complaint to local store vs Annual Budgets)
For my music collection, it seems prudent to have the File Name include the Artist+Album+TrackNo+SongName, because it would be catastrophic if things got copied into the wrong directories - happens more than you think when using the Touch Pad - and then you would have to open up/listen to every file to figure out what it was and where it went?!
By contrast, while the same logic should apply to my Photography Collection, the fact is that my photos are Too Large in Number, and Too Dynamic to keep up with such a filing scheme.
So in that case, I just come up with a comprehensive Directory Structure, and hope I don't misplace "dsc012345.jpeg" !!
(Although, for photos that I want to keep forever, I do tend to rename them like... "PHOTO_2013_Arizona_GrandCanyon_SouthRim_Sunset_05.jpeg")
I'm sure this entire topic is highly debatable, but my larger concern was just making sure that by introducing SPACES or SPECIAL CHARACTERS (e.g. apostrophe) that I wouldn't be causing heartaches down the road on either my MacBook Pro, or if I ever have to share data with a Windows user.
Sincerely,
Debbie
