What is a .XDelta file?
XDELTA is a binary patch in VCDIFF format, often used to patch game ROMs.
- Did you know
- xdelta turns the difference between two files into a small patch.
- xdelta was created by Joshua MacDonald and uses an algorithm inspired by rsync to find the differences between two files.
- Because an xdelta patch stores only what changed, it can be a tiny fraction of the size of the file it updates.
- What Analyser reads
- Identify and read more game and emulator files: Unity asset bundles, Unreal cooked assets, CISO/CHD disc images, FMOD/Wwise sound banks, Spine skeletons and atlases, GameMaker/LDtk/TIC-80 projects, Minecraft Anvil regions, Warcraft III maps, Ren Py and RPG Maker data, extra console ROMs (Atari, PC Engine, Master System/Game Gear, WonderSwan, 3DS homebrew), xdelta/Basis patches and emulator saves and movies.
- Depth of analysis
- .XDelta is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .XDelta file
- Drag a .XDelta file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
