How to open APLN file?

The main problem with Adobe InDesign 3rd Party Extension is that the APLN file is incorrectly associated with programs. This is manifested by the fact that APLN files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the APLN file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Adobe InDesign

An often overlooked issue is to make sure that Adobe InDesign is installed on the computer. To do this, enter the name Adobe InDesign into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file APLN.

Programs to open APLN file

Remember to download programs supporting APLN files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Adobe InDesign with APLN files

If, despite the installed application, the APLN file does not start in the Adobe InDesign application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Adobe InDesign application as the default for handling the APLN file.

Step 3. Update Adobe InDesign to the latest version

If, however, after binding Adobe InDesign with Adobe InDesign 3rd Party Extension there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Adobe Systems Incorporated page and install.

Step 4. Check for the following problems with the APLN file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

Very often, the file may be size 0 or incomplete. This suggests truncating the APLN file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our APLN file. As a result of the scan, sometimes it is not possible to recover APLN files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of APLN file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair APLN file corruption. You can restore the file from a backup or use Adobe Systems Incorporated help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted APLN files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the APLN file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
