Description

Hi,

Picture browser seems to load the entire directories recursively before displaying interface, this could take a lot of time even with a SSD.

It should list 1st level raw and then background update subdirs (like number of files).

Config: Raspberry Pi 4 8GB Raspbian 10 MotionEye 4.3.2 Motion 4.3.2 Image File Name: %Y%m%d/%v/%H-%M-%S-%q Storage: Kingston A400 SSD SA400M8/240G M.2 2280 with Argon ONE M.2 case

Regards,

Contributor guide

Research direction
Investigate the directory listing logic in the picture browser. Replace the recursive listing with a lazy loading approach: show first level directories immediately and asynchronously count files in subdirectories. Consider using callbacks or threading to avoid blocking the interface.
