Well I see this is still a bit of an issue - and it is unfortunate that what seems like a simple fix of a check box that asks if you want everything moved along with the folders (in my case) that are being renamed probably isn't as simple as it seems to be by someone who doesn't know anything about programming..
I get the problem, and I agree that it should have a solution.
I think that it would be good if they could add something to MC that will accomplish your goal: You have sidecar files with your albums that you want to move with the files,
whenever they're moved.
It is, unfortunately, not so simple from a UI design point of view. Here's the basic problem: The Rename, Move, and Copy Tool doesn't care about folders as a "thing". It cares about files. Truthfully, even the filesystem underneath of Windows Explorer (and the Finder on OSX) doesn't consider folders to be "things" either (not in the same sense as files are). Folders are simply a construct of the filename, and indexes.
If you go to the command prompt and "rename" this file:
M:\Audio\Music\P\Pink Floyd\Ummagumma\2\04 - Sysyphus (Part 4).flac
to:
M:\Audio\Music\P\Fink Ployd\Ummagumma\2\04 - Sysyphus (Part 4).flac
It "moves" the file, but that's really just a rename. They're the same thing. The filesystem "creates" the "Fink Ployd" folder. It doesn't "do" anything to the old folder, other than remove the file from the index. That's why, with symbolic and hard links, a single file can "exist" in two different folders simultaneously without occupying additional storage space on disk. Because the "folder" is really just an index of what files it contains.
So... Here's the problem: MC doesn't know, for sure, that those files belong to the files you're moving. It works on the files one-by-one, it only knows about the files you've imported into MC, and specifically selected to be moved, and it doesn't know about what might be "still to come" in the batch file list you've selected. Yes, in your case, it is a single album in a single folder and you want to move it. But what if:
* That folder contains other files, unrelated to the ones you are moving. People don't always store things as neatly as you do. What if they have things strewn about, with multiple, unrelated albums (or movies or whatever) dumped into the same directory. In the real world,
lots of people have piles of junk like this. We nerds may consider them animals, but they exist and JRiver has to think about them.
* What if you have files selected together, which are all in a common directory, and you're "splitting them up". Say, for example, you have an album that is a double-CD. Right now, disc one and two are together in the same directory, and have a bunch of sidecar cover art files and log files and whatnot. But, you've tagged the files nicely in MC and so now you're going to Rename them into subdirectories for each disc. Where does it move the sidecar files? Just with whatever ones happen to come first in the list? Does it not do it at all then (which would be inconsistent and confusing)? Does it throw an error or something (hopefully before causing havoc)?
Everyone in this thread, I think it would help if we can try to work together to propose a cohesive suggestion towards this goal. It annoys me too, even though I don't care about most of those sidecars. I'd rather it have some way to handle them and delete the ones I don't want, frankly!
But, I get that it is a problem. I just don't know that there is a "perfect solution". Or, at least, we haven't found it yet. Can we try to find it, and discuss it? If so, I bet it'll get some traction.
