File System

Custom LDAT File Management

Jellux completely bypasses modern file system bloat. Using our custom LDAT engine, the OS manages direct LBA sector allocations using minimal 3-byte magic header tags. It includes built-in program launching (.JEP), direct sector manipulation, and kernel-level guardrails preventing accidental destruction of core OS sectors.
