About BAK2 files
The .bak2 file is a secondary world backup format used primarily by the sandbox game Terraria and also by Starbound. It functions as a final emergency failsafe to prevent data loss. The main disadvantage of the current format is that it is proprietary and completely unreadable by standard operating systems or text editors. It exists solely to replace a primary save file if severe corruption occurs. Users need to convert this file when their primary game save is broken, but because it is a closed binary format, standard online converters fail to process it. The best practical conversion targets are the original native formats, such as WLD for Terraria or WORLD for Starbound, which simply requires an extension change. This file format is difficult to open or convert natively because only the original software can properly read or export the complex map coordinate data. However, convert.guru offers a pragmatic workaround. Just drag and drop your file to identify the format, view it, and convert it when possible. We can still identify the file format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your BAK2 file, detects the exact format, and lets you read the text inside.
Users also converted BAK, PLR, WLD, TWLD and BAK1 files.
