What is a APX file?
Borland C++ Appexpert Database Format, identified by the APX extension, is a Data Files type and includes 6196 files.
With the creation of the Borland C++ Appexpert Database Format (APX), Embarcadero introduced file format along with 8 programs built for their use.
APX files are supported by Windows. You can open a APX file using one of 2 programs, for example Borland C++ and C++ Builder.
How to open a APX file?
The most common reason why a APX file cannot be opened is the absence of required software. To fix this, select a compatible program from the list. Then visit the official developer website via the provided link, download the program, and install it on your system.
The most popular programs for working with APX files are Borland C++ and C++ Builder. To get the latest version of Borland C++, open the Micro Focus website where a universal installer for all operating systems is available.
Once setup is done, your operating system should assign Borland C++ as the default app for APX files.
Make Borland C++ the default APX viewer
Changing the default program in Windows
- Start by right-clicking on your APX file and selecting the "Open With" option. From there, click "Choose another app" to continue;
- Inside the popup window, scroll through the list of applications and specifically choose Borland C++ as the application to associate with your APX file;
- Check the "Always use this app" checkbox and click "OK".
Change the default app to open files on Mac
- Right click or use Control + Left Click on the desired APX file to access a dropdown menu of actions;
- Select "Open in application" and click "Other";
- Scroll down to the bottom of the window, where you will find the "Enable" menu. Default, "Recommended Programs" will be selected;
- In this menu, choose "All Programs" and navigate to Borland C++. Check the box next to "Always open in app" to make it the default program.
Convert to and from APX
If a APX file is difficult to handle, you might try converting it to formats such as JPG, JPEG, PDF, BMP or similar, which may be easier to work with.
Please note that after converting a APX file, some functionality may differ from the original. However, in many cases, it can be converted back to its original format.
