Bin may refer to any of the following:
1. A .BIN file is usually considered to be a binary file, which is used for many purposes as it is associated with many different programs. Trying to view the contents of a .BIN file using a text editor only shows garbage. Determining what application the .BIN file belongs to is difficult as well. Viewing the file code may help if any clue to its origin is found in the ASCII portion of the file.
.BIN files can contain information for various functions, including images or sound for an application, a ROM for an emulator, or CD images. Some antivirus programs use them, as does Microsoft Windows, and even some printer drivers.
2. The /bin directory is found on Linux computers and stores all binary executables. This directory includes all the command line commands and other binary executables.
3. Bin is also an abbreviation sometimes used for the Windows Recycle Bin.
