SQLite 3 data format
File type category:
Database file
Date updated: November 25, 2018
The cls file extension is related to the SQLite, a relational database format.
The format used by SQLite database files has been completely revised. The old version 2.1 format and the new 3.0 format are incompatible with one another.
The new database file format uses B+trees for tables. In a B+tree, all data is stored in the leaves of the tree instead of in both the leaves and the intermediate branch nodes. The use of B+trees for tables allows for better scalability and the storage of larger data fields without the use of overflow pages. Traditional B-trees are still used for indices.
The new file format also supports variable pages sizes between 512 and 32768 bytes. The size of a page is stored in the file header so the same library can read databases with different pages sizes, in theory, though this feature has not yet been implemented in practice.
