Linear Region File Converter for Minecraft (GUI)

Based on the original project LinearRegionFileFormatTools

What is Linear Region Format?

Linear region format saves about 50% of disk space in OW and Nether and 95% in The End.

This repository hosts tools to convert between .mca and .linear.

Features:

• Saves about 50% of space when compared to Anvil
• Reads and writes whole files, so it will actually be faster than .mca on a spinning HDD (way less IOPS than .mca)
• Replaces symlinks with files, thus allows caching on HDD
• Uses slightly more memory than Anvil - it has to store the whole region file in memory for individual chunk access
• Much simpler format - about 600 lines of code vs about 1000 LoC for Anvil
