Yardmaster,
It looks like devices from different manufacturers have slightly different instructions. Here is the procedure for your phone:
1) Open the My Files app
2) Tap the "Internal Storage" folder to open it
3) Tap "Android" and then "Data"
4) Scroll down and tap "com.spindance.mthremote"
5) Tap "Cache" and then you should see the file with the export data
6) The file will have a name that begins with "wifiDcsExport-" and then a date and several other numbers
7) "long press" the file name and you should see a menu at the bottom of the page.
8) choose the share icon from this menu and you should be able to email the file to yourself
Steps 3-6 should be the same for every device. It's just the first 2 steps that might look different. I believe there are several apps for Android devices that would also work. Just go to the app store and search for "file manager".
