What is a .UMD file?
UMD is a disc image of a Sony PlayStation Portable Universal Media Disc, though PSP dumps circulate more often as .iso or .cso. The same extension is also an e-book format popular on Chinese feature phones.
- Did you know
- The Universal Media Disc was Sony’s compact optical format for the PSP, launched in 2004.
- A single-layer UMD held about 900 MB and a dual-layer one up to 1.8 GB, encased in a small protective cartridge unique to the PSP.
- UMD movie releases dwindled in the late 2000s as studios dropped support, and the format faded out as PSP production ended in 2014.
- 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. Scene and scenario files share the .scn extension across unrelated engines, so it is resolved on its bytes: a Godot binary scene (RSRC header) is named as one, and the strategy-game scenarios (OpenTTD, Age of Empires, SimCity 2000) and plain-text scenes (Orbiter, Behringer X32) are told apart from it. Custom Player Models .cpmmodel avatars - the standalone model the Minecraft mod exports, and what the Blockbench plugin reads and writes - are identified too.
- Depth of analysis
- .UMD 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 .UMD file
- Drag a .UMD 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.
