I have a large number of message folders in MacOS Mail (v. 9.3, El Capitan 10.11.6), with a pretty deep hierarchy in places--I have folders in folders four or five deep in some places. (I am talking about folders in the Mail GUI at this point, not operating system folders/directories on a drive.)
Sometimes a folder just disappears, and what's happened is that it's become a subfolder of some other folder. (It's possible that I do this by accident with uncautious use of the mouse, but I don't think that's it. I think Mail just gets confused and does stupid things sometimes.)
I know that the folder and its messages still exist, because if I open the message search box, I can find messages, and they are listed as being in a folder with that name. I want to drag the folder back to where it belongs, but sometimes I can't find out where that folder is. Since I have so many folders and subfolders, poking through every folder in Mail to find out where Mail decided to move the folder in question is time consuming.
Is there any way to find a folder, by its name, for example, in the Mail folder hierarchy?
Even if there's no tool in Mail to do this, maybe there's a kludgey way to do it by searching through Mail's data files on disk using
find, etc. Maybe there's some graphical utility that I don't know about that will help.
