on my old mac i used basecamp v3.1.1 which will not open in my new mac, so I downloaded the new version v4.8.12. it works fine and has all my old points, routes etc. I cannot find the file where my collection is saved, even after searching for alldata.gdb it is possible i saved to a custom location 12 years ago..... Any other ideas how to find this file? Is it hidden in the new basecamp? Can I delete the old program without risking losing any of my old data? I did make a backup file of the data on the new basecamp. Im a bit lost since I haven't used this software for over 5 years, between my old gps breaking and not having updated basecamp..
