What is C4 file?

The C4 file has been categorized as Raster Image Files. The author of this format is JEDMICS. Additionally, the Raster Image Files category contains 522 of other files. JEDMICS Image Format is supported by 2 operating systems. These systems consist of Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. The XnView application is recommended to open the file. It was released by Pierre-Emmanuel Gougelet. There are also 3 alternative programs to handle the C4 file. The Trix Drawing Center, Unlimited Slick! ViewPlus programs will also handle the file when the XnView program does not fulfill its role.

How to open C4 file?

The most common problem when using JEDMICS Image Format is that a specific C4 is not associated with the program. This causes the file C4 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the C4 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. The easiest method is to use the system search engine by entering the program name XnView in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file C4 with XnView. Later in this article you will find a list of programs that can open C4 files.

Step 2. Create association of XnView with C4 files

However, it may happen that the application itself does not cause the C4 file to open in the XnView 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. 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. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the XnView application as the default for handling the C4 file.

Step 3. Update XnView to the latest version

The fault may also lie with the XnView program, it is possible that JEDMICS Image Format requires a newer version of the program. 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 C4 file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This suggests truncating the C4 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 quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the C4 file that we want to open. Sometimes virus-infected C4 files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the C4 files changes over time. 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. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged C4 files. You can restore the file from a backup or use JEDMICS help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted C4 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. These directories are write-protected to them and it's very hard to fix this problem. It is best to move C4 to a different directory.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the C4 file again. However, some background programs may block the C4 file while scanning. If this does not work either, restart the device.
