## Design ## Reference material
At a high level, littlefs is a block based filesystem that uses small logs to [DESIGN.md](DESIGN.md) - DESIGN.md contains a fully detailed dive into how
store metadata and larger copy-on-write (COW) structures to store file data. littlefs actually works. I would encourage you to read it since the
solutions and tradeoffs at work here are quite interesting.
In littlefs, these ingredients form a sort of two-layered cake, with the small [SPEC.md](SPEC.md) - SPEC.md contains the on-disk specification of littlefs
logs (called metadata pairs) providing fast updates to metadata anywhere on with all the nitty-gritty details. Can be useful for developing tooling.
storage, while the COW structures store file data compactly and without any
wear amplification cost.
Both of these data structures are built out of blocks, which are fed by a
common block allocator. By limiting the number of erases allowed on a block
per allocation, the allocator provides dynamic wear leveling over the entire
filesystem.
