Anybody know what the *.stk files are for? Mine are all empty, and showed up with the latest release ( 2.58 ) of survce. It must use them for something, maybe for staking, because the date on them changes with the job, bu mine all have 0 bytes.
Also, I think the *.sys files are new with the 2.58 release. It looks like they contain the projection info, geoid, etc.
