I made a trip a while ago using the Copilot GPS navigation application. Now I want to map the GPA tracking data, but I can't find any by browsing the memory with a Windows PC. I looked for the data with an Android file explorer app, and I found the data! I finally recovered the data by emailing the data files to myself. So does Android make certain kinds of files invisible to a desktop PC? I could understand hiding system folders or files, but why hide the GPS data?
