Well, it depends on how much free space there is on the filesystem, and how "fragmented" it is. If the filesystem is 90% used, the dirprefs code doesn't have much room to use disk blocks for new directories in an efficient way. But it's probably better than nothing. It's very difficult to say in advance, so I'd suggest you just try it.
