As you can tell by now, there is a lot of stuff happening under the hood in ROWB.
All of these different monitors, managers and processes, were built to ensure the safety of your data at all times.
In particular the folder monitor and cache manager, work in tandem to ensure that the game has completely finished writing the save data to the file, to avoid conflicting with the game, once the backup process beings.
This is of particular importance, since two programs effectively are trying to access the same single file at the exact same time, which if not done correctly, can cause either or both programs to crash, horribly,
possibly even corrupt the save data beyond repair.
Everything that ROWB does, is built with the sole purpose of keeping your world saves as safe as possible, without causing conflicts or otherwise interferring with the running of the game.
In effect, ROWB, for intents and purposes, is designed to be "forgotten" about, once you start playing. Just leave ROWB running in the background while you are playing and ROWB will silently but
surely and safely generate backups of your worlds, every time you hit the save button in the game.
Everything in ROWB is event driven, so if nothing changes, then nothing happens. There is no timed checking of the save files every 60 seconds or something crazy like that.
When you close ROWB's window, the application does shut down, however if the backup manager is still processing, it will remain active in the background until it completes it's current work and then terminate.
