As far as I know, and as far as I've ever heard anyone say, there's a whole *one* Fomor spawn that can drop the Extra-Fine File. Go to Lufaise (at night of course), and go to east end of the tier 5 orc area (roundabout the center of the map, a little west from the lake).

There's a watch tower there, and it'll have three fomors in it - WAR, BST, and SMN (and thus two pets as well). The WAR in that tower, as far as I've heard, is the only enemy that can drop the Extra-Fine File. Haven't heard anything about it dropping from non-WAR fomors, or from WAR fomors elsewhere.

On the bright side, the drop rate doesn't seem to be too bad, drops once every few kills. Only problem is, of course, the whole undead-only-at-night issue.

Tuning Out is significantly less hassle. You only have to farm up *one* rare-ex item for that one (from ... Mantrap, I think is the name, the flytrap enemies in Misareaux near Riverne or Sacrarium). You also have to kill off a group of bees - who build up sleep/lullaby resistance, be careful - in Yuhtunga. Other than that it's just a few buyable items and a lot of running around.
