bundle files are usually compressed with lz4hc (mostly level 12). But tbh I don't have compressed any unity game since months.

Example "Universe Sandbox 2" (because I have installed it right now as the only unity engine game).

Code:

Universe Sandbox x64_Data\StreamingAssets\aa\StandaloneWindows64\defaultpersistent_assets_all.bundle

Code:

Streams: 2401 / 2401
Time: 00:00:02 (CPU 00:00:15)

Size: 248 MB >> 326 MB

Used unity plugin with lz4hc,l12 setting and lz4 library 1.9.4.

Does the plugin not work on .resS , .assets ,.resouce files ? I was trying it on a game that doesn't have .bundle file, maybe that's why it didn't work. Anyway thanks for the help

resS and assets files have no compression.

.resource files are either FMOD audio or videos.

The only file that is compressed which is in the <game name>_Data folder is data.unity3d.
