libfuse is an open-source library that provides the reference implementation of the Linux Filesystem in Userspace (FUSE) interface. It enables developers to create fully functional file systems without writing kernel-level code. The library handles communication between user-space applications and the Linux kernel's FUSE module. It provides functions for mounting, unmounting, processing file system requests, and returning responses. Developers can choose between a high-level synchronous API and a low-level asynchronous API. Its callback-based architecture supports custom file systems for cloud storage, archives, encryption, and virtual data. libfuse is widely used across Linux distributions and supports flexible file system development.
