Deleting files in Windows XP extremely slow
Why does deleting files (and at the same time, emptying the recycle bin) takes so long on Windows where it would be near instantaneous on another OS like Linux? This behavior is definitely present on all Windows and seems to be more prominent when deleting a lot a small files (as expected) or a folder containing such files and in exponential time (not quite expected).
Can this be ameliorated? (I don't know, maybe setting registry entry HK_USERS/haveOneOrMoreCoffeeBeforeDeletingAnyFile to false?)
