The latest software does not fit on your device's internal memory

Fenix 5S. At version 22.20 (2a587ca). Tried to update via Garmin Express and get above Subject Line error and to contact support. I have hard reset device several times, deleted all activities several times, turned off automatic updates and when I view space via Windows Explorer, it shows 50.9MB used space, 3.28MB available. I believe the update is just over 4MB, which may be the issue since there is only 3.28MB available. No activities/data remains on the watch or maybe they're stuck in some sort of recycle bin on storage. How do I make room for update? Been through the reset process several times, as I mentioned. Thanks

Thanks Richard. I did check the storage and saw that something was taking substantial space. The GARMIN folder only had 3.7MB. I did run windirstat and found something eating up 47.2MB. I ran chkdsk on…

You might check the storage used on your watch from a PC, via USB (Mass Storage mode). Mine has 45MB space left. There might be Windows or MacOS hidden directories with content. What size is your Garmin directory?

If you manage to see it, try to have a look in the LOST.DIR.

You might also run a disk check.

If you are using windows, i suggest a tool name windirstat, it will find every directories sizes and you might find the abnormal heavy ones.

Thanks Richard. I did check the storage and saw that something was taking substantial space. The GARMIN folder only had 3.7MB. I did run windirstat and found something eating up 47.2MB. I ran chkdsk on the directory and it converted lost chains to files. I deleted the FOUND.000 and freed up 46.9MB and was able to install the update from Garmin Express. Please see my attached images. Not sure what the <Unknown> is but even after I ran the chkdsk, it still appears, and may be growing again. Thanks again.

WinDirStat is slow.

I recommend: Directory Report

I don't know for sure but you might need to install the firmware (i guess it is done now) then try to reset the watch (delete the settings from the menu, then hard reset). Just be aware that any customisations will be lost :(

Looks like you got it but on mine I removed all of the languages that I don't think I'll ever use, got me just enough space. Drawback is that now I have to be vigilant to prevent them from being re-installed.

But wow I did the chkdsk and my found000 was 47 mb! Great tip, thanks, I've been wondering why there was only room for like a weeks worth of activities.

Glad you got it sorted. Remember to always remove the device from the computer properly (Remove USB Device -> unmount the filesystem) before unplugging it.

On the Fenix 3, the watch would perform some filesystem check during bootup. If the unknown file does not grow, then just leave it I guess, but you can eventually have a look in the log files of the watch and see is anything is wrong during bootup
