: Indicates the binary is optimized for 64-bit Windows operating systems, allowing it to handle larger memory buffers and take advantage of 64-bit CPU registers for faster processing. Stack Overflow Common Uses for the Win64 Binary lz4/lz4: Extremely Fast Compression algorithm - GitHub
LZ4 is an extremely fast, lossless compression algorithm developed by Yann Collet. It is designed for high-performance scenarios where decompression speed is critical, often reaching the limits of RAM bandwidth on multi-core systems. Version 1.8.3 Context lz4 v183 win64

Before diving into the specific version, it's crucial to understand the technology itself. LZ4 is a lossless data compression algorithm that belongs to the LZ77 family of byte-oriented compression schemes. The algorithm's core design focuses on an extraordinary trade-off: sacrificing a bit of compression ratio for immense compression and decompression speeds.
LZ4 allows you to trade speed for slightly better compression ratios. Version 1
The 1.8.3 update focused on stability and minor API refinements rather than a total overhaul. Notable changes included:
Obtain the lz4_v1_8_3_win64.zip from the official LZ4 GitHub Releases. Extract: Unzip the folder to a directory like C:\lz4 .
Fix : The base LZ4 v1.8.3 CLI processes files using a single core. If you need to compress massive multi-gigabyte datasets using all CPU cores simultaneously, look into using APIs or wrapping it in a PowerShell parallel loop.
