It's made to run on an FTP server (like a Raspberry Pi), for use with Reolink NVRs and security cameras to automatically delete old recordings, and organize the files, etc. The script runs once, so you have to use a cronjob to execute periodically.
You can setup the script to run automatically by typing crontab -e in your linux terminal, and adding a line like this:
*/5 * * * * python3 /home/pi/manage_uploaded_files_task.py >> /home/pi/manage_uploaded_files_task.log 2>&1 # Runs the script every 5 minutes, and logs to file
Requires Python 3.9. Requires the humanize library, which you should be able to install with 'pip3 install humanize'.
You can use Python 3.7 (default on Raspberry Pi), but you'll have some errors to fix, mainly related to static typing.
So for example, you'll have to change. list[RecordedFile] to just list for statically typed return types.
