Not sure if you're talking about the same thing. You, vocalpoint, are talking about the files added to the library (
like audio, video, photo) which can be moved using the
rename, move, & copy files... tool.
I guess what audunth is talking about is the library itself, which is managed via
File -> Library.
If I'm guessing right, audunth is pointing out a thing I was wondering about myself, too. As he said:
Not a huge problem, but I like to keep things as neat as possible [...]
The only reason I could guess why MC behaves as it currently does, is that JRiver is going to assure that there is
always a default library at a default place. If MC runs into some kind of problems it offers a startup dialog where we can select to make MC use the default library. If it is not there for some reason, this function would not work proper. Maybe for this we are not able to move the default one...
Again:
Not a huge problem, [...]
