The Initial Thought about Graph-based File System

Around 2005, Dan was organizing his personal data and a problem happened. Some files should be in a folder and should be also in another folder, and he thought of graph; a graph should solve the issue instead of a tree.

During those days, Dan was using Windows and symbolic links, hard links weren't quite familiar and the issue happened. With Linux, people use symbolic links and hard links to solve the issue, although in Linux the file system is still a tree but with those links, nodes in tree can be linked together to appear at different locations.

The bottom line is graph is being utilized more and more, especially after 2000 until now and more in the future.
