Microsoft now allows just about any file type to be stored in SkyDrive. At the time of designing Walk-Run-Bike-Drive, only a few basic file types could be uploaded to SkyDrive, for example, TXT for text files, JPG for photos, etc.
Walk-Run-Bike-Drive imports and exports GPX file types. GPX stands for GPS Exchange Format. In the early days of Windows Phone, SkyDrive would not allow GPX file types. To get around that, we made our file type “.GPX.TXT” since text files were allowed.
Fast forward to present day: Now we can store GPX file types in SkyDrive. And our new Windows 8 app, Route Planner 8 (for your Windows 8 tablet or desktop) does open and save GPX file types to SkyDrive.
To make the sharing of routes between your tablet, desktop, and phone easier, we’ve updated the phone app to use “GPX” file types instead of “.GPX.TXT”.
Confused? Well, basically this update simply means you can create a route on your Windows 8 desktop, save it to SkyDrive, and open it on your phone without needing to rename or move any files.
Also, routes and tracks you find on GPS sharing sites can be opened on your phone without renaming the file.
For compatibility, Walk-Run-Bike-Drive will still find and read the previous file type too. But new routes saved to SkyDrive will be “GPX” type. This is handled automatically by the app.
