Battery died towards the end of a long MTB ride. I have charged, restarted, synced, etc and there is no data. There is also no evidence of the FIT file in my Activities folder (or TempFIT folder), however I have a file in the NewFiles folder with the date/time of my ride as a TFF file. I haven't found any online information about TFF files- what is this? Can I recover my ride somehow?
