Sorry - what is I assume, a very basic question. I am not a big docker user so bare with me

I have installed your fantastic work, following the dense instructions to the letter. All worked great. Logon, getting data etc Have a beautiful dashboard and stats for the past month.

Then I wanted to change the compose.yaml to download the fit files as well. I want them because I want to use them in another mapping program.

I updated the compose so KEEP_FIT_FILES=True and

• /mnt/GPXShare_rwx/garmin-fetch-data/fit_filestore:/home/appuser/fit_filestore
  and checked I had write access to this directory

then ran
docker compose run --rm -e MANUAL_START_DATE=2025-08-01 garmin-fetch-data

and it went one by one though by August activities logging as it went along on the teminal

2025-08-05 17:53:03,773 - INFO - Success : Activity ID 19925964607 stored in output file /home/appuser/fit_filestore/20250802T101423UTC-walking.fit

restarted docker container and new data shows in grafana

However - no files are in /mnt/GPXShare_rwx/garmin-fetch-data/fit_filestore nor can I find a directory /home/appuser/fit_filestore. Where would they be? I expected to be able to do

ls -al /mnt/GPXShare_rwx/garmin-fetch-data/fit_filestore - nothing
ls -al /home/appuser/fit_filestore - also nothing?

I am running this on proxmox lxc with docker

thanks - and thank you for this great work. Now on to learning grafana
