File attachment save location

I am new to ERPNext and recently installed v12.19. I am very impressed so far.

Having said that, where are file attachments saved? If they are saved into the database, is there a way to have them save to the filesystem instead? I prefer to keep the database as small as possible and large attachments in the database runs contrary to that.

If attachments cannot be saved to the filesystem instead of the database, I request that as a feature enhancement.

Anyway, thank you in advance for your prompt response.
