I am using Netview for the first time to connect to the TR3. I was able to connect and view the files (624 of them). I am wanting to delete those files to clear up memory in the TR3. My question is when I start a job with base/rover on the LS+ I have been working on ( I downloaded and archived on the LS+} does it create a new base file which would be downloaded at the end of the day in the LS+? I guess what am asking is whether it is a good idea to clear 3 years of base files out. Also I am going to download the 624 files to an external hard drive before deletion. Mike
