File extension a01 is used by following file type(s):

file type 1 description:
Default file extension for .a01 file type:
Split Multi-volume ARJ compressed file archive (part 3)
The A01 file extension is associated with ARJ, once very popular archiving program for MS-DOS. An *.a01 file is one part of a multi-volume compressed ARJ archive.

ARJ file extension is used for the native format of ARJ archiver. ARJ is a file archiver that compresses files into a disk space saving archive. It is fast, reliable, and has a rich set of features which include Windows 9x, Millenium long filename support, file version management, data damage protection, ANSI escape sequence display handler, configurable command options, multiple volume archives (archives that span diskettes) and much more.

Some ARJ files can be parts of a multi-volume sequences. In ARJ you can split a huge archive to a few smaller files, which are called volumes.

ARJ archiver does use the following sequence:

  • .arj for first volume
  • .a00, a01, a02 .... etc. for any additional volumes

In order to unpack the multi-volume ARJ archive, you need to place ALL of the split parts in the same directory and start extraction of the first volume (.arj). The program will automatically use all of the parts to extract the content of the archive.

Ada programming language source code file definition and 8 other file types and linked programs information.


File extension a is used by following file type(s):

 file type 1 description:
Ada programming language source code file
The A file extension is associated with Ada, is a structured, statically typed, imperative, and object-oriented high-level computer programming language based on Pascal. It was originally designed by a team led by Jean Ichbiah of CII Honeywell Bull under contract to the United States Department of Defense during 1977–1983 to supersede the hundreds of programming languages then used by the US Department of Defense (DoD). Ada is strongly typed and compilers are validated for reliability in mission-critical applications, such as avionics software. Ada is an international standard, the current version (known as Ada 2005) is defined by joint ISO/ANSI standard.

Alpha Channel image data
The Alpha Channel is this nifty storage area in your image's file for non-visible picture elements. Think of it as your picture's own little private utility closet/filing cabinet. The .psp picture file has these extra goodies stored in its Alpha channel that can just travel around with the picture (unseen until you need them) as a part of the file.

Major items of interest that get stored in the Alpha Channel are Selections, Masks and Creator Information. We can save this stuff to the Alpha channel and then dig it back out later to reuse for editing that picture or using in our other images.

Assembly source code
An assembly language is a low-level language for programming computers. It implements a symbolic representation of the numeric machine codes and other constants needed to program a particular CPU architecture. This representation is usually defined by the hardware manufacturer, and is based on abbreviations (called mnemonics) that help the programmer remember individual instructions, registers, etc. An assembly language is thus specific to a certain physical or virtual computer architecture (as opposed to most high-level languages, which are usually portable).

Assembly languages were first developed in the 1950s, when they were referred to as second generation programming languages. They eliminated much of the error-prone and time-consuming first-generation programming needed with the earliest computers, freeing the programmer from tedium such as remembering numeric codes and calculating addresses. They were once widely used for all sorts of programming. However, by the 1980s (1990s on small computers), their use had largely been supplanted by high-level languages, in the search for improved programming productivity. Today, assembly language is used primarily for direct hardware manipulation, access to specialized processor instructions, or to address critical performance issues. Typical uses are device drivers, low-level embedded systems, and real-time systems.

A utility program called an assembler is used to translate assembly language statements into the target computer's machine code. The assembler performs a more or less isomorphic translation (a one-to-one mapping) from mnemonic statements into machine instructions and data. (This is in contrast with high-level languages, in which a single statement generally results in many machine instructions. A compiler, analogous to an assembler, is used to translate high-level language statements into machine code; or an interpreter executes statements directly.)

Many sophisticated assemblers offer additional mechanisms to facilitate program development, control the assembly process, and aid debugging. In particular, most modern assemblers (although many have been available for more than 40 years already) include a macro facility (described below), and are called macro assemblers.

File extension aspx is used by following file type(s):

file type description:
Default file extension for .aspx file type:
Active Server Page Extended ASP.NET script file
The .NET pages, known also as as web forms, are the main building block for application development. The Web forms are contained in files with an .aspx extension. These files typically contain static (X)HTML markup, as well as markup defining server-side Web Controls and User Controls where the developers place all the required static and dynamic content for the web page.

The ASPX file extension is used for files that are of the Active Server Page Extended format. These are internet webpages which are made using ActiveX scripting, and which are based on the Microsoft ASP.NET programming framework. These webpages are generated by Internet servers. The ASP code is created by the Internet server, and then is interpreted as HTML by the web browser.

The native application, that uses ASPX script files is ASP.NET server (mainly Microsoft IIS - Internet Information Server). ASPX scripts files can be written in Microsoft Visual Studio and WWW pages, that are written in ASP.NET and used ASP.NET, can be viewed in Internet browser such as Internet Explorer, Firefox, Opera, Chrome.
