XLocate
Conveniently search and update any volume
...XLocate automatically recognizes through libmagic the most widespread locate database formats (GNU locate, slocate and mlocate/plocate). XLocate’s versions from 0.81 keep track of your disk partitions using their UUID, so you don’t have to specify anything in order to add them to the catalogue. You can conveniently search for files using any of the locate tools, even if not installed in your path. You can also transparently create and update indices from within the application.
