auracomp 2.0

auracomp is a simple and fast command-line tool for compressing and decompressing files using the formats supported by AuroraLib.Compression.
It supports automatic format detection for decompression and a wide range of supported algorithms commonly used in video games.

Quick Use (Drag & Drop)

To quickly decompress a file, simply drag and drop it onto auracomp.exe.
The tool will automatically detect the format, and if successful, create an output file next to the input file with ~output appended to its name.
