How to open ADU file?

The most common problem when using Addict User Dictionary Format is that a specific ADU is not associated with the program. This causes the file ADU to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the ADU 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 Addict

The first step is to check if the computer has the Addict program installed. The easiest method is to use the system search engine by entering the program name Addict in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open ADU files.

Programs to open ADU file

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

Step 2. Create association of Addict with ADU files

If the application is or has been freshly installed, but the ADU file still does not use the Addict program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the ADU file with the Addict program.

Step 3. Update Addict to the latest version

The fault may also lie with the Addict program, it is possible that Addict User Dictionary Format requires a newer version of the program. In this case, use the Addictive Software website or update the program from the application.

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

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the ADU file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file ADU or the program directory. Sometimes virus-infected ADU files cannot be recovered, so make a backup in advance.
Older version of ADU file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular ADU file corruption. The easiest way to restore the file is from a backup or by contacting Addictive Software, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted ADU 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.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. Copying the ADU file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the ADU file again. Some anti-virus or backup software may occupy the ADU file for a certain period of time. If nothing helps, please reset the device.
