However, modern video games are massive because they contain high-resolution assets—textures, audio, and videos—that are often already compressed. For example, a .png texture or an .ogg audio file is already compressed using specialized codecs. Trying to compress these files again with standard tools yields almost no size reduction; the data is "incompressible" to a general algorithm.

This is where xtool enters the picture.

While most users will only encounter xTool through repacks, advanced users can utilize the library to create their own compressed backups. Note: This requires command-line proficiency.

Here is where xTool enters controversial territory. Many modern games (looking at you, Denuvo-wrapped titles) include custom archive checksums. If you modify one byte, the game refuses to load.

xTool contains optional routines to:
