What is a .UBulk file?
.UBulk is a file in the Game engines category. Analyser identifies it and reads the metadata in its header, right in your browser.
- Did you know
- UBULK holds the bulk binary data of an Unreal Engine asset, large content like high-resolution textures split out of the main .uasset.
- Separating bulk data lets Unreal stream big assets in the background and keep the core .uasset small.
- Datamining an Unreal game means recombining a .uasset with its .uexp and .ubulk to recover the full asset.
- What Analyser reads
- Identify game-engine assets: Unity (UNITYPACKAGE, .resS resource streams), Unreal Engine (UASSET, UMAP, .uproject / .uplugin descriptors, .ubulk bulk data, .ufont fonts, .locmeta / .locres localisation, .ushaderbytecode shaders), Godot (TSCN, TRES), Minecraft asset metadata (.mcmeta) and language files (.lang / .lng), and Bink Video 2 (.bk2) cutscenes.
- Depth of analysis
- .UBulk 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 .UBulk file
- Drag a .UBulk 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.
