.AAE file extension was developed by Apple and is very popular. It is categorized as a Data file and comes in the XML format.

Open AAE File

The file contains edit that is made to an image with Photos app and it is used on iOS devices.

The file extension is used for transferring non-destructive edits made by a user to .JPG images on an iOS device to the macOS system. You can find AAE files accompanying the images for which they contain edits.

As an Apple device end user, you might have come across the extension on your device, especially when going through your image folder. The extension is never available on windows device since Windows does not show it by default. If you want to transfer a photo with the .AAE file extension from an Apple device to a Windows device, the file will first be converted to a JPEG before being transferred.

It makes possible to keep the original photo image and any edit you might have made without overwriting it.

They are used by both iOS 8 and OS X 10.10; the former is the very first Apple device to use the file extension and the other ones came to the picture much later. If you are importing pictures to a Windows operating system from an iOS device, the JPG file will get transferred, but it will be left behind.

As a result, you will lose the edit. You can equally erase the .AAE files without deleting your pictures, but it will lead to the removal of any edit made to the pictures.

It is referenced by the Photo app anytime you are opening the JPG file associated with it. The data associated with it is saved in the form of XML and can be opened using a Notepad, TextEdit or any other text editor. In the next section of this write-up, we will look into various ways by which you can open it.

How to open .AAE extension

They can be downloaded easily if you do not have them on your device already. Bear in mind that Notepad comes as a default addition to Microsoft devices.

For those using macOS, you can easily open the .AAE file by using tools like Apple Photos, Apple TextEdit or any other text editor that is compatible to Apple devices. Those using Linux Operating System can go for virtually any text editor to open it, like AbiWord, OpenOffice Writer, Boxer, Jarte, CodeLobster PPHP Edition, ConTEXT, WordPerfect and so on. Many of them are available for free download, but you will have to pay to access some other ones; the paid ones are WordPerfect, Boxer, EditPlus and even NoteTab.

File type: FPK Archive


What is

The A file extension is closely identified with the 32- or 64-bit FPK Pascal (Free Pascal) compiler application. The software supports various types of processors like PowerPC, Intel x86, Sparc, AMD64/x86 64, and Motorola 680x0.

The compiler associated with the A format file can also be deployed in a wide array of computing platforms such as FreeBSD, Linux, SunOS (Solaris), NetBSD, DOS, Classic Amiga, BeOS, QNX, Mac OS Classic, Mac OS X/Darwin, MorphOS, and 32-bit Microsoft Windows Operating Systems.

This compiles supports the excellent language syntax compatibility with the Turbo Pascal 7.0 (TP 7.0) including the Delphi development language. This compatibility extends to interfaces, widestrings, ansistrings, exceptions, rtti, and classes.

For Apple users, the application incorporates the Mac Pascal compatibility mode which also has a built-in support for global properties, operator overloading, and function overloading among others.

The generation of the A file extension along with runtime libraries and packages of the compiler are covered by modified Library GNU Public License in order to make the use of static libraries in the creation of programs.

The action of the compiler is usually controlled by two distinct methods, command line options and the use of the fpc.cfg configuration file.
Initially, the compiler attempts to check the contents of the configuration file and then verifies for command line options respectively.
By following this process, the possibility of setting basic options in the configuration file including defining specific options is made easier when dealing with some programs or units.
The ppumve program takes every unit file then modifies the contents prior to compilation to identify the unit code in the library.
The new unit files will take the PPU file extension which can be changed by using the -e command option. Static libraries take the
A file extension while shared libraries are assigned the SO file format under the Linux Operating System environment. For OS/2 and the Microsoft Windows NT platform, the DLL file extension is used.

By using the RIFF format, audio and visual data in the movie chunk is encoded or can be decoded by a codec.
The codec is then able to translate between raw data and the compressed format used within the chunk.
A file with the .avi file extension can carry audio and visual data in the chunk in any compressed form.

File type: ASP.NET Source


What is

The .aspx file extension is an ASP.NET Source File. It pertains to Web pages and source files created using the ASP.Net Framework application.

The said program is a component of the .Net technology of Microsoft and is employed in creating rich and dynamic content for Web pages that allow the execution of embedded scripts at a rate much faster than any other online server. Web pages with the .aspx could be opened or viewed using any Web browser operated by Mac or Microsoft systems.

This is because the execution of all the scripts in the .aspx Web page is made on the server. The browser is therefore enabled to display Web page as a plain HTML.

File type: Adobe Illustrator File


The AI file extension is a type of vector image specifically created with the Adobe Illustrator image editing application. This file format is made up of paths or lines connected by points as opposed to bitmap data which includes text, color, and objects.

It is a type of illustrator drawing that can also be accessed with other applications developed by Adobe like Photoshop.

However, when opening the image with programs like Photoshop, it is converted into a raster image which essentially transformed it from a vector image format to a bitmap file. In computing terms, vector graphics like the AI file extension utilize geometric primitives like curves, lines, points and polygons in representing computer graphic images.

These shapes are all established through mathematical equations. This graphics type is complementary to raster formats which represent pixel arrays and is normally associated with photographs. Vector images are more applicable when creating drawings and shapes.

It uses the mathematical formula in attempting to reconstruct the image on the computer screen.
This is usually achieved by producing the best possible quality image based on the given screen resolution derived by the mathematical data. The mathematical formula determines where the dots on the computer screen would be placed in order to achieve the best result in displaying the image represented by the AI file extension.
Essentially, the dots are arranged by the formula in such a way that the lines would be as clear as possible. In vector graphics like the AI file extension, the formula produces images which are scalable to practically any detail and size. The quality of the displayed image is dictated by the maximum resolution supported by the computer monitor including the file size of the vector data that would be required to generate the same image.
Printing this image on paper would produce a sharper image with a higher resolution compared to its onscreen representation.
