If you are a fan of Lara Croft’s gritty Siberian adventure, Rise of the Tomb Raider , few things are as frustrating as settling in for a gaming session only to be greeted by a cryptic error message. Among the most notorious is the “BigFile000” error .

This error typically manifests as a pop-up stating: “Failed to open BIGFILE.000” or “Could not find BigFile.000.” It brings your game to a screeching halt—often during startup or when loading a new area.
