You are right. There have been recordings under that folder on the SD card. Probably the NAS wasn't available at some times when recordings started and therefore the recordings have been stored on the SD card. I moved them now to the NAS and the disk space is freed. Thanks.

I have libreelec running on a raspberry 3 and it reports that my SD card is quite full (10.3 GB of 12.5 GB used in mounted folder /storage)

But I checked this as well and there is not pending file deletion (plus I did a reboot and the issue remains).
Codefind /proc/*/fd -ls 2> /dev/null | grep '(deleted)' => (nothing)Does anybody have an idea what else could cause this? Where are the 10 GB clogging my SD card?
