ADC

ADC (ArchivedDataCodec) is an open-source archiver and compression tool designed for transparency, performance, and portability across Windows and Linux.

The ADC format uses a simple 8-byte header and a linear archive layout, making it easy to implement and audit while still providing efficient compression.
