How Cryosparc Live watches new files in directory?

Hi! I would like to know, if possible, how ‘watch’ mechanism works in Cryosparc Live?
Is it something like ‘inotify’ which monitors filesystem events for specific folder. Or it something like re-scanning folder contents once per time period (for instance 1 second)?
I want to understand which impact it can have for shared (network) file systems.
