Change File Name Format

LINDALJOINT

I suggest you use the Windows Properties - Date Created and or Date Modified in Explorer Details view to determine when an activity file was created on the computer.

What if multiple activities are synced from a single day? Or in instances where I am unable to sync every day. All the files will have the same date modified. Is there a way to raise a change request to get this resolved?

I apologize, I must have been very tired and not comprehended your question. Please see the FAQ: Why are activity files from my ANT device not being stored on my computer once I have uploaded them to Garmin Connect using Garmin Express? The fit files with the desired name format are saved in another location after a successful sync. The article applies only to ANT devices. Files from the Edge can be retrieved from the internal memory.

Not sure what you mean. The above is a file name from my 910. One thing I have noticed is that local time is not used so the date for us folk here in the Land of the Long White Cloud usually have the date as the day before. That being said, it's never to hard to find out which one is which.

And Curt, the date an activity file was created on the computer may bear no relation to when the activity was carried out.

It would at least provide some reference to the last time the device was synced. I have been looking into this and it appears the files names created are different even for the same type of devices, .TCX vs. .FIT. The 310XT creates a .FIT file that still uses the date format where as the 910XT creates a .FIT with an arbitrary file name. All .TCX devices use the date format so far. The main purpose for this location is for Backup so as it sits it is fulfilling its design.

Now that's worthy of a chuckle LOL! Is there no 'authority' in Garmin where the changes are documented.

The point still remains, Garmin Express has changed the file name structure from that of ANT Agent, and that does make it a little more challenging. Knowing when the device was synched offers little in the way of information as to when the activity was carried out

I'd agree. I think it's kinda silly that the current file names are not human-usable. I do understand the formatting and naming convention from a technical sense, but it still doesn't really justify that it makes no sense these days. It was much easier when it had the date/timestamp built into the file name.

If we're talking about these kinds of names, the filename is a date/timestamp, just compressed to fit into 8 characters (on the 920XT at least).

4BOC0931.FIT
4BP72419.FIT
4BPI1348.FIT
4BQH2814.FIT

#0-#2 are the days since 1999-07-22 in base 36 (4BO). #3 (C) is the hour in base 36. #4-#7 (0931) are the minutes+seconds. "4BOC0931" => "2014-11-24 12:09:31"

Granted, it's not "at-a-glance human readable" but everything useful is there.

Yeah, I've just noticed my guesswork went horribly wrong as we crossed the month boundary. Ta for that.

I ended up create an extension for windows explorer that allows to view details about the fit file in the preview pane.

If anyone is interested the installer or source code can be downloaded from http://www.johntindell.co.uk/2014/11/fit-file-previewer-for-windows.html
