You're here because you have a file that has a file extension ending in .a. Files with the file extension .a can only be launched by certain applications. It's possible that .a files are data files rather than documents or media, which means they're not meant to be viewed at all.
what is a .a file?
A C/C++ static library file is used by integrated development environment (IDE) kits that were developed with a set of integrated functionalities which can be used to develop C/C++ applications. The built-in functions and procedural systems required by these C/C++ application development projects need to reference the data stored in these C/C++ static library files. The content of a C/C++ static library file includes source code pertaining to certain application functionalities and information headers that are used as reference data by the associated C/C++ application development project and the C/C++ integrated development environment kit. The data stored in a C/C++ static library file is integrated with source code compilation standards and implemented with data encoding specifications used to store data in the A file format. These C/C++ static library files are appended with the .a extension.
how to open a .a file?
Launch a .a file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .a file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .a files aren't yet associated with it. In this case, when you try to open a .a file, you can tell Windows which application is the correct one for that file. From then on, opening a .a file will open the correct application.

Microsoft Visual Studio
Microsoft Visual Studio
Microsoft Visual Studio is an integrated development environment (IDE) produced by Microsoft. It has a code editor that supports syntax highlighting and code completion using IntelliSense for not only variables, functions and methods but also language constructs like loops and queries; includes a debugger that works both as a source-level debugger and as a machine-level debugger; includes a host of visual designers to aid in the development of applications and other tools. Visual Studio permits developers to write extensions for Visual Studio to expand its capabilities. These extensions are linked to Visual Studio and extend its functionality. Extensions come in the form of macros, add-ins, and packages. Macros represent repeatable tasks and actions that developers can write programmatically for saving, replaying, and distributing; add-ins gives access to the Visual Studio object model and can interact with the IDE tools; and packages can create designers and other tools, as well as integrate other programming languages.
gVim is a free, open-source, highly configurable, feature-rich portable text editing software for programmers. It is known as the “programmer’s editor”. You can write codes efficiently with syntax highlighting in various languages, and has features such as search and replace for regular expressions. It has pop-out menus for easy access with a layered interface to enable you to work on multiple documents. gVim is the improved version of vi editor that is run on most Unix systems. It is bundled with another version of gVim to work in a Notepad-like manner called Easy Vim or evim or gVim Easy. It runs on Windows Vista, Windows 7, Windows 8, Windows 2000 and Windows XP. The latest version is version 7.3 with changes such as text concealment, Lua interface, blowfish encryption, swap file encryption, undo for reload, persistent undo and Python 3 interface.
Notepad is a basic text editor used to create plain documents. It is commonly used to view or edit text (.txt) files, and a simple tool for creating Web pages, and supports only the basic formatting in HTML documents. It also has a simple built-in logging function. Each time a file that initializes with .log is opened, the program inserts a text timestamp on the last line of the file. It accepts text from the Windows clipboard. This is helpful in stripping embedded font type and style codes from formatted text, such as when copying text from a Web page and pasting into an email message or other “What You See Is What You Get†text editor. The formatted text is temporarily pasted into Notepad, and then immediately copied again in stripped format to be pasted into the other program. Simple text editors like Notepad may be utilized to change text with markup, such as HTML. Early versions of Notepad offered only the most basic functions, such as finding text. Newer versions of Windows include an updated version of Notepad with a search and replace function (Ctrl + H), as well as Ctrl + F for search and similar keyboard shortcuts. It makes use of a built-in window class named edit. In older versions such as Windows 95, Windows 98, Windows Me and Windows 3.1, there is a 64k limit on the size of the file being edited, an operating system limit of the EDIT class.
Be careful not to rename the extension on .a files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.
what is a file extension?
A file extension is the set of three or four characters at the end of a filename; in this case, .a. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
