I'm getting super frustrated with continual errors uploading longer ride files from my Edge 520.
It happens on longer rides when the battery is low at the end of the ride. Hit save, history shows a saved file. But, you when I select it, you can't access any data.
If I try to manually upload it I get and error message 'we don't support the file type you tried to upload'
Any ideas?? All the online software to fix files seems to be PC based and I'm on a Mac.
Thanks
thank you for the feedback
congratulations with the triathlon 
recording to your fit file ended abruptly without proper closing and missing summary
would put the cause with the latest firmware,…
Thanks! I think it worked... 
try this
your file can be structural repaired with help of Fit File Tools's section remover (removing nothing)
ran your file through Fit File Tools's section remover for you
check this…
never seen this fault before...a strange one
some data records had randomly value 0xE5 replacing the original data
happened at km 23.5 ish
updated affected values, recalculated file checksum
