just a thing to add that you should be aware of if the field [date imported] is important to you and any fields that you have opted to not write to embedded tags in the file itself for that matter (player stats for example). By running "autoimport" - not import just a folder by the way - will import these files provided that their drives paths and files extentions are included in the import configuration beforehand.
They will be added as newly imported however.
Unlike the folder watching systems provided by many other applications, Media Center's background Auto-Import system relies, in part, upon a system called File System Events that is provided by your Operating System to allow it to respond to any changes made in a watched directory. This allows Media Center to react instantaneously when any changes are committed to a watched directory
the key here is
File System Events. If for some reason the OS does not issue this "event", (or it is slow in doing so) either you have to wait or you have to force the import. On local drives connected to the media server PC this works pretty well. On networked drives, NAS, external drives etc., slow can be, ahem, hours. It is only immediate when/if a FSE is issued.
The best way to move or rename files is through the Rename, Move Copy command from within Library tools. Presets can be made for this. Its a very powerful tool. If you are moving drives or changing path names, this is very handy. You can also "re-point" the data base from here without reimporting.
As ferday already mentioned, changes made through the internal explorer of JR is also immediate. What I do is right click on a track=>Locate and choose Internal. And you go directly to the tracks in question without scrolling.
Wish external changes were dependant on some other mechanism, but I'm sure there are reasons for this
PS- posted at the same time -- the Name field is the metadata name and not the windows filename btw
