The '''Smart File System''' (SFS) is a journalling filesystem used on [[Amiga]] computers. It was designed for performance, scalability and integrity. It could use block sizes ranging from 512 (2^9) to 32768 (2^15) bytes with a maximum partition size of 1 TB (1024 GB) or more depending on the block size.

Good performance of the filesystem is realized by grouping multiple directory entries into a single block and by grouping meta data blocks together into clusters. A bitmap is used to keep track of free space, and file data is kept track of using extents arranged into a [[B-tree|B+ tree]] structure.
