I made these diagrams to generally explain to a college class how file storage layers work on a drive and now when you delete/format the filesystem the file data remains. I couldn't find one online, so made one. What do you think? Any significant issues?
@climagic VFS is also more of a “container “ for the filesystems that have the “specific” functions that are attributed to them. You can have applications simply bypassing the entire filesystem stack and have their own method of storing and retrieving data. Databases do a lot of work on raw block devices without using any filesystem for example
