Not (I want to say never) "each individual file". There's a bit more to it.
Never before seen versions of popular games still surface from time to time and when that happens some reshuffling of existing sets for that game is bound to happen. For example, what was "Set 2" now becomes "Set 3". Then both your sets 2 and 3 stop working - the new set 2 needs new files, but the old set 2 simply needs to be renamed.
Another situation is MAME being updated for accuracy, requiring data that used to be hard-coded in MAME, like graphics palette data from a PAL or GAL chip (or whatever is in it). Even for a game that has been supported for a decade or longer. Those chips simply weren't dumped when that particular game was first dumped way back in the day. So that game would stop working once that data is properly dumped and becomes a "required file".
This is all in the official mame.net FAQ though, which you should definitely read.
