I believe that you can put your files into a tree structure where each subfolder represents a different metafield.
The metafields will then be set when the files are imported.
You might have to have "don't let MS manage the files" (or whatever it is called)

You would need to get your files into the correct tree structure and use some tool to remove the common meta data from the filenames prior to the import.

Suggest you set up a small tree to see if you can establish the method before spending time organising your files (search the forum for clues; I've never used this)

Sciurius may have some tools (not sure how he spells his username)
