I have a field team using a Trimble Geo XH from 2008.
My usual workflow is to have them email me the raw GPS files, which I copy into a "GIS Folder" for import to Pathfinder where I process it. I then transfer the .cor file to that GIS folder. The output is 8 files that together make the GPS data file. I email the those 8 files to the team to have them copy/paste them on the the GPS unit.
They pointed out to me that the files I sent do not contain a ".CAR" file (no, not ".cor") but there is one currently on the GPS unit. I do not believe I have the ability to recreate a CAR file
What information is in the ".CAR" file? Can we remove it? Is it important? Is it optional like .prj .sbn and other components of a shapefile are?
Edit: I had the team remove the .CAR file from the GPS before copy/pasting the 8 GPS files over. Data collection appeared to go fine all day. By the end of the day when they backed up the data, the .CAR file had returned, however H-Star processing options are no longer available!
