Yacc Yet Another CSO Compressor offers a straightforward and effective way to reduce file sizes, making data storage and transfer more manageable.

Yacc is a compression tool developed by kapoue3 for use in CSO files. This tool is designed to reduce the size of CSO files without affecting their functionality.

Yacc utilizes various compression techniques to reduce the size of CSO files, including Huffman coding, LZ77 compression, and run-length encoding. These techniques are applied to the data within the CSO file, resulting in a significantly smaller file size.

Huffman coding is a lossless data compression technique that creates variable-length codes for each symbol or character within the data. This technique provides an efficient method for storing and encoding data.
LZ77 compression is a lossless data compression algorithm that uses sliding windows to search for repeated patterns within the data. Once a pattern is found, it is replaced with a reference to the previous occurrence, resulting in a smaller file size.
Run-length encoding is a lossless data compression technique that replaces repeated adjacent symbols or characters with a count of the number of repetitions. This technique is effective on data that contains long strings of repeated characters.

With Yacc, users can enjoy smaller CSO file sizes without sacrificing any functionality or quality.

Note: Yacc should only be used on personal backups and not on copies obtained illegally.
