Files that contain the .a file extension are most commonly associated with the Ada programming language for saving of its source files. These files contain structured, object-oriented computer programming files that have been written in the Ada language.
The Ada language was originally created for the US Department of Defense. Files with the .a extension are commonly used in mission-critical applications and in avionics software.
The .a file extension may also be used for static library files. These files contain information that is referenced by a C or C++ source file. The static library allows the source to reference the library in order for faster loading of the associated application or function.
