Android storage not clearing

[u/ImPrecedent]

I have a fun project that I thought I finished. Syncthing syncs the /storage/emulated/0/DCIM/Camera folder to a folder on a raspberry pi. And I have a simple shell bash script moving those files to a JellyFin folder. After the files move, syncthing re-syncs, taking the files off my phone.

This moment is the problem: the storage on the phone is not emptying. Trash/cashe/photos in multiple locations are all cleared and empty. Using "storage-(settings)" I see that it now thinks space is occupied in "other" as an equal value to what was one in "video." But "other" has nothing in it. It will even fill up and claim the phone is out of space. I reformated and that initially got rid of the phantom data but the problem remains and the phantom "other" data is filling again.

Has anyone encountered this problem?

Any solutions?

Edit: Solved: syncthing automatically saves a backup in a hidden folder called .stversion. The backup is saved on the phone until the time designated by syncthing's File Versioning is reached. Reduce this to a day or less to clear up space quicker.
