How to open C4U file?

The main problem with OpenClonk Update System is that the C4U file is incorrectly associated with programs. Thus, when you open C4U, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the C4U 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 OpenClonk

In this case, you should first verify that the OpenClonk application is installed on the computer. To do this, enter the name OpenClonk into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file C4U with OpenClonk. Below you will find a list of applications that support C4U files.

Programs to open C4U file

Remember to download programs supporting C4U files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of OpenClonk with C4U files

However, it may happen that the application itself does not cause the C4U file to open in the OpenClonk application, but you can set it manually. 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 select the desired program. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the C4U file with the OpenClonk application.

Step 3. Update OpenClonk to the latest version

If, despite the association of the OpenClonk program with the OpenClonk Update System file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Open Clonk Development team website or update the program from the application.

Step 4. Check for the following problems with the C4U 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:

Very often, the file may be size 0 or incomplete. This suggests truncating the C4U file contents when downloading or copying. Downloading the file again should fix the problem.
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. For the best results, we will scan the entire operating system, not just our C4U file. As a result of the scan, sometimes it is not possible to recover C4U files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of C4U 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.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged C4U files. You can restore the file from a backup or use Open Clonk Development team help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file C4U except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
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 C4U to a different directory.
This problem only occurs with more complex files. In this case, the C4U file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the C4U file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
