I haven’t had my tablet long enough to get out and record a track yet. But just going thru the GPX menu, I found that same folder that your recording was found in without having to connect the tablet to the PC.
Tap the GPX icon at the top of the map screen >select Load File. In the top right of the screen is a hamburger menu (3 lines) tap that, select what directory you want to access, the T865 or your SD card. Selecting the T865 shows all of its File folders. The Recordings folder is there.
There are 2 Settings menus, one for DMD and the other for the tablet. You can also get to the tablets and SD cards files and folders from the tablets settings menu without going thru the Load GPX function. At the bottom of the screen, tap on the 4 stacked boxes. Select Settings> select Files. That’s the same menu that you see when you are accessing it thru the GPX Load function. Use the hamburger menu in the top left to change directory.
It sounds like you’re wanting to move files from the Recordings folder of the Tablets directory to a GPX folder you’ve made to the SD cards directory. When you tap on any file in either the SD card or the Recording folder, it just gives you the option to open in DMD or Google Wallet. I’m not finding a way to transfer files in the Recordings folder of the T865 to the SD card internally “with the tablet”.
The only way I’m finding to do that is when it’s connected to the PC. Drag and drop or copy and paste from one directory to the other.
