Why does unreal engine separates “.ubulk file” and “.uexp file”?
Is this for reducing disk seek time?
As far as I know, yes. The separation of “.ubulk” and “.uexp” files in Unreal Engine is done in part to help reduce disk seek time.
By separating the binary data from the export data, Unreal Engine can optimize the loading of game assets. When an asset is needed, the engine can first load its export data, which is smaller and faster to load. Additionally, separating the binary data from the export data can make it easier to manage game assets. It allows developers to modify and update assets without needing to recompile the entire game, which can save time and reduce the risk of introducing new bugs.
