David, your TomTom uses Linux so it treats files differently, if you remove the .chk files from the device it won't even boot up as they are rather important!
data.chk is the file containing the POI Warning sounds, open the voices folder and you will find even more .chk files as all the voice files are of the same file name, leave it well alone or you will have a device that won't boot - Mike
