cleared the ACTIVITY folder with about 30-40 files when I went on the run

-- I've spent about 15 mins looking around Connect/Express and can't figure out how I check the free memory on my FR 25...

-- I'm a mac user

-- The activity was probably in the high-average duration and distance, not too out of the ordinary

-- There was one actual break in the middle and then a handful of pauses waiting for crosswalk lights

• the amount of FIT files in the ACTIVITY folder on your FR35
  • (when folder contains many fit files time for a backup/clean operation)
  • 28 files currently - need to clean out?
• the amount of FREE memory on your FR35
  • (when low FREE memory, check above and below answer)
  • 2.9 MB
• are you a MAC user
  • (empty BIN on device)
  • Yes, MAC user
• was this activity with a long duration or distance compared to previous activities
  • ( long ones use more memory )
  • Yes, this was my long run for the week - about 3x my usual runs
• was this activity with a pause somewhere during the activity
  • Yes, pauses before starting intervals

Issue :

• there was one byte wrong in the file
• it looks like happening while writing the fit file after stopping the activity
• the original file checksum is the same as when after repairing the faulty byte
• there must be many users with faulty data without even knowing ?

original file : checksum                              repaired file : checksum (same as in the original file !)

Lots of FIT files 

I'm not sure how to check the memory

I use MAC and now have emptied the BIN

Not a longer activity

Yes there was a pause during activity

I think it's was caused by low battery and/or too many files on my device.

I think it was because I paused it a couple times. I did a longer trail run and stopped to eat/drink.

deleted all old files and restored factory settings

now it's happened again, not too long after, so clearly amount of files is not the problem

6 FIT files in the activity folder

don't use a Mac

it goes straight from the watch to garmin connect on a Samsung phone

it wasn't a long distance.

4.7MB of 5.6MB available.

paused a couple of times when running
