Many people are confused when they encounter .bin and .cue files on their computers, and they don't know how to open and use them. These two types of files often appear together and are closely related to disc images and audio data. They require specific tools and methods to process them.
The essence of BIN files
In essence, a BIN file is a binary image file that completely copies every data on a storage medium, such as a CD or DVD. This type of file was extremely popular from the late 1990s to the early 21st century and was often used in software distribution, game backup, and music CD copying. It is not limited to audio, but may also cover videos, programs, or mixed content.
Due to its binary nature, BIN files cannot be opened directly with regular players or decompression software. You need to know exactly what type of data it covers so you can decide what to do next. If it is an audio CD image, the .cue file is usually its "instructions".
The role of CUE files
CUE files are plain text description files that do not store actual audio or video data. Its function is to guide the playback software or virtual optical drive how to correctly read the BIN file. For example, it will accurately mark the starting position, duration, gap and track information of each audio track in the BIN file.
If there is no CUE file, then a BIN file with many songs may be regarded as a complete and indivisible audio piece when played. In the early 2000s, when people used CD burners to back up music CDs, they often generated these two files together to ensure that the burned new disc was exactly the same as the original.
Using virtual optical drive software
The most common way to deal with this pair of files is to use virtual optical drive software, which can simulate a physical optical drive in the operating system. Daemon Tools and Alcohol 120% have been widely used since the 2000s.
You only need to run the software, click "Load Image" or a similar button, and then select the .cue file. The software itself can automatically identify and associate the .bin file in the same directory. After the loading is successful, an additional CD-ROM drive icon will appear in "My Computer", and the content of the image will be displayed in it.
Direct playback and format conversion
If you simply want to play the audio, some professional media players can directly read the .cue file. For example, Foobar2000 and VLC Media Player support this function. Open the .cue file in the player, and it will list all the audio tracks according to the index and play them.
If users want to transfer music to a mobile phone or MP3 player, they can convert the loaded virtual disc content. You need to use format conversion software, such as EAC or dBpoweramp, and just choose to output it into a common format such as MP3 or FLAC. This process is equivalent to ripping CD tracks as digital files.
Possible problems
The most common problem during operation is that the CUE file does not match the BIN file. This may be because after the file is renamed, the BIN file name pointed to in the CUE file is not modified simultaneously. You can use Notepad to open the CUE file and check whether the file name referenced in the "FILE" line is accurate.
Another issue is software compatibility. On the macOS operating system, you may have to use other tools, such as some open source command line tools. In newer Windows systems, when installing older versions of virtual optical drive software, you must pay attention to whether it is suitable for the current system architecture.
Process other types of BIN files
It should be noted that files with the .bin suffix are not necessarily CD images. They may also be router firmware, game ROM, or binary data of a certain device. Before trying to open it with the above method, it is best to make a preliminary judgment based on the file source or size.
If it belongs to the category of firmware files, generally speaking, you have to use the specific burning tools provided by the manufacturer to perform the flashing operation. If you are targeting ROM files for old game consoles such as Nintendo, you must use the corresponding emulator to load and run them. When dealing with unknown .bin files, figuring out their exact source is a critical and important step for security.
