What is an APT file?

APT files mostly belong to Maven by Apache. An APT file contains the markup of a piece of documentation written in Almost Plain Text markup language. Maven Java project build management, reporting, and documentation tool generates HTML documentation from such APT files. Another type of APT file is a punch tool used by Alphacam computer-aided woodworking software. AutoPlay Media Studio application for creating custom autorun menus saves an AutoPlay menu project in an APT file. A raster image encoded using Adaptive Prediction Trees image coding method are saved in APT files before they are converted to a PPM bitmap.

How to open APT files

You need a suitable software like Maven to open an APT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your APT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a APT file directly in the browser:. Just drag the file onto this browser window and drop it.

APT file format details:

The file format determines how the data is stored in the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. When there is a problem with a file, the first step to solving it is to determine the file format. In the following you will find our evaluation of the APT files:

The APT file extension is not common and includes various formats for various programs. The two most popular formats are as follows:

50% of all APT files are based on the popular MP4 file format. MP4 is a multimedia container format used to store video and audio and allows streaming over the Internet. These files are binary files, so they do not contain text, but only cryptic characters. The average file size is 24 MB with most files being between 5 MB and 52 MB in size. The file type is a fairly new file format. The keywords ftypisom, isomiso2avc1mp41, \tkhd, lmvhd, moov and trak are typical for these files. Files like these are about movies.
8% of all APT files start with the bytes 1 2 crucial for this file format. The contents of these files are easily readable with a text editor. A typical file size is 10 KB. The following keywords are characteristic: APT~1 3, ISO 8859-1 and SilviA.

All other APT files (42%) have no consistent format, often, for example, Android PandaHome theme, DOC and Apt. Often described as seniority, list, download, service, pregnancy or data. Just click the "Choose your .apt file to analyze" button on this page to find out what your APT file is.
