Open DEX File

DEX extension files have various format and application options, some of which are listed below:

Dalvik Executable File

A DEX extension file is an executable file saved in a format that contains compiled code written for Android, Google's Linux-based mobile phone platform.

Android is the operating system that some mobile devices use to function.

In other words, it is about everything that you can see and with which you can interact from the screen of your computer.

DEX files are usually common for developers and designers of Android applications.

These can be verified when you use Android Studio (SDK).

More about Android Studio

Android Studio is the official integrated development environment (IDE) used to develop apps for Android.

Based on IntelliJ IDEA's powerful code editor and developer tools, Android Studio offers even more features to improve your productivity when building Android apps.

It is technically called a 'Dalvik Executable', and can be interpreted by the Dalvik virtual machine.

DEX files can be created manually or by automatically translating compiled Java programs.

Multiple DEX files are compressed into a single installable APK extension package, which is, in any case, the final Android application file.

Disketch

In this second case, the DEX file is a disk label project created by the Disketch label design software.

Disketch lets you easily add your own images and text to CD, DVD, or Blu-ray disc labels and covers, so you can quickly create your own labels and covers.

The DEX file saves the layout for a CD or DVD and can include imported text and images, it can also be printed using a standard printer or a printer that supports disc labels.

Because Disketch has been updated, it now uses the DEPROJ extension for disk label projects.

Given the above, the DEX format is deprecated but can still be opened by current versions of Disketch.

Excel Spreadsheet

In this section, a DEX file is a spreadsheet file created by Microsoft Excel or exported by another spreadsheet program, such as OpenOffice Calc or Apple Numbers.

A spreadsheet is used to organize, analyze, manipulate, and visualize data, in the form of tables with rows and columns.

Excel is the most widely used spreadsheet application in the world, ahead of Numbers, OpenOffice and LibreOffice.

It is included in all editions of the Microsoft Office suite and is used in home, academic, and business environments.

DEX is similar to XLSX files but in binary file format.

Similar to XLSX, data is stored in rows and columns in a DEX file.

Although DEX files are also from Microsoft Excel, these are less popular and less well known.

By comparison, the XLSX file format is the default choice for saving Excel workbooks.

DEX files have been marked deprecated and are no longer supported in newer versions of Microsoft Excel.

DEX files can also store math functions, graphics, styles, and formats.

DEXIS Digital X-ray File

In the latter case, the DEX file is an X-ray image saved in the proprietary X-ray format used by the DEXIS Digital X-ray system for dental imaging.

DEXIS Digital X-ray systems is a manufacturer of X-ray capture devices with various products that complete a wide range for dental workers.

As its acronym indicates, the DEX file captures dental X-rays and saves them in a digital format, which is proprietary.

Software to open and work with a DEX file

Due to the fact that DEX files can take different formats, it is necessary to make sure of the format of that file that you have in your hands, since using inappropriate software can cause damage to the file that can be irreparable.
