-# Fragment Store
-
-Fragments are are pieces of information split into Metadata and Data.
-They can be stored seperated or together.
-They can be used as a Transport protocol/logic too.
-
-# Store types
-
-### Object Store
-
-Fragment files are stored with the first 2 hex chars as sub folders:
-eg:
-`objects/` (object store root)
-  - `5f/` (first 2hex subfolder)
-    - `4fffffff` (the fragment file without the first 2 hexchars)
-
-### Split Object Store
-
-Same as Object Store, but medadata and data stored in seperate files.
-Metadata files have the `.meta` suffix. They also have a filetype specific suffix, like `.json`, `.msgpack` etc.
-
-### Memory Store
-
-Just keeps the Fragments in memory.
-
-# File formats
-
-Files can be compressed and encrypted. Since compression needs the data structure to funcion, it is applied before it is encrypted.
-
-### Text Json
-
-Text json only makes sense for metadata if it's neither compressed nor encrypted. (otherwise its binary on disk anyway, so why waste bytes).
-Since the content of data is not looked at, nothing stops you from using text json and ecrypt it, but atleast basic compression is advised.
-
-A Metadata json object has the following keys:
-- `enc` (uint) Encryption type of the data, if any
-- `comp` (uint) Compression type of the data, if any
-- `metadata` (obj) the

-### Split Metadata

-file magic bytes `SOLMET` (6 bytes)
-
-1 byte encryption type (`0x00` is none)
-
-1 byte compression type (`0x00` is none)
-
-...metadata here...
-
-note that the encryption and compression are for the metadata only.
-The metadata itself contains encryption and compression info about the data.
-
-### Split Data
-
-(none) all the data is in the metadata file.
-This is mostly to allow direct storage for files in the Fragment store without excessive duplication.
-Keep in mind to not use the actual file name as the data/meta file name.
