How to open CDU file?
The main problem with CDU Paint Image Format is that the CDU file is incorrectly associated with programs. This is manifested by the fact that CDU files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the CDU 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 XnView
The first step is to check if the computer has the XnView program installed. This can be achieved by typing XnView into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file CDU with XnView. Below you will find a list of applications that support CDU files.
Programs to open CDU file
Remember to download programs supporting CDU files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of XnView with CDU files
If, despite the installed application, the CDU file does not start in the XnView 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. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the CDU file with the XnView application.
Step 3. Update XnView to the latest version
If, despite the association of the XnView program with the CDU Paint Image Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Pierre-Emmanuel Gougelet website or update the program from the application.
Step 4. Check for the following problems with the CDU file
The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:
The affected file may be 0 KB or smaller than expected. Usually this applies to CDU files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. 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. However, it is important to scan the entire system, not only the file CDU or the program directory. However, remember that not every infected CDU file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the CDU files changes over time. 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.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair CDU file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
The program can also signal the fact of encryption. The encrypted CDU files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
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. It is best to move CDU to a different directory.
This problem usually affects 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 you have to wait for the session to the file CDU to close. However, some background programs may block the CDU file while scanning. If this does not work either, restart the device.
