My new understanding of how the "Drives & Devices > Explorer" function works opens up a whole new set of workflows I can use.
I no longer need to import a movie, for example, and then fix tags and metadata. I can RIP a movie to a non-imported location, fix/update any tags I wish to, run "Get Movie & TV Info" against the file even, then when I am happy, import the file in situ and then move it, or use the RM&CF function to move it to a Auto Import watched location.
This may not seem much, but for example I could RIP movies on my Workstation, without cluttering up my local MC library (I use DVDfab to RIP directly, rather than inside MC, at the moment anyway), update all metadata and collect Cover Art etc., and maybe even additional images, trailers, or other files related to the movie, and once it is all set up, move them to the HTPC movie location using my Workstation MC installation, direct to the share drive. Now that "Move all files" works using the Explorer View, MC would move all ancillary files I add. Cool.
I'm still thinking about how I might use this functionality.
I note that there is nothing in the Wiki with regard to how the Explorer functionality works, or how it may be used. I always thought it was just an internal version of Windows Explorer. It is so much more!
Thanks for being persistent on this fix JustinChase.
