Briefly speaking, open source file systems are a subset of file systems, that is, all open source file systems belong to the category of file systems, but not all file systems are
open source.
Unlike proprietary file systems , open source file systems refer to file system solutions whose source code is open to the public, allowing anyone to view, modify, distribute, and use them.
In addition, open source file systems are designed to promote technological innovation, reduce the cost of use, and improve the customizability and flexibility of the system.
