The file fg-optional-bonus-soundtracks.bin is a specific data component commonly associated with high-compression "repacks" of video games, most notably those distributed by the group FitGirl Repacks. This file functions as an optional installer component, allowing users to choose whether or not to include additional audio content—such as high-quality soundtracks or bonus music—during the game installation process. The Role of Optional .bin Files in Repacks
In the world of digital game distribution, "repacks" are versions of games that have been heavily compressed to reduce the download size. Because lossless audio and bonus content (like digital artbooks or soundtracks) can take up several gigabytes of space, repackers often split these elements into "optional" files.
Customization: By keeping the soundtrack in a separate .bin file, users with limited data or disk space can skip downloading it without breaking the core game installation.
Verification: During the installation of a FitGirl repack, the installer (often using the QuickSFV tool) checks the integrity of files like fg-optional-bonus-soundtracks.bin to ensure no data was corrupted during the download. How to Use fg-optional-bonus-soundtracks.bin

Checksum Mismatch: If the installer says the file is corrupted, it means the download is incomplete. Repackers usually provide a .bat file (like Verify BIN files before installation.bat) to check the files against their original hash.
Missing File: If you want the soundtrack but the installer doesn't offer the option, ensure the file is named exactly fg-optional-bonus-soundtracks.bin. If the name has been changed (e.g., by a browser adding a (1) to the end), the installer will ignore it. Why Is It a ".bin" File?
The .bin extension stands for "binary." In this context, it is a container format that holds compressed data. It isn't a file you "open" with a media player; rather, it is a library of data that the installation software (like Inno Setup) reads and unpacks into usable audio files.
