How to open D4C file?

The main problem with Dataphor Data Format is that the D4C file is incorrectly associated with programs. This is manifested by the fact that D4C 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 D4C 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 Dataphor

In this case, you should first verify that the Dataphor application is installed on the computer. This can be achieved by typing Dataphor 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 D4C with Dataphor. Below you will find a list of applications that support D4C files.

Programs to open D4C file

Remember to download programs supporting D4C files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Dataphor with D4C files

If the application is or has been freshly installed, but the D4C file still does not use the Dataphor 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 window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. 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. Checking the "Always use the selected program ..." box will permanently associate the D4C file with the Dataphor program.

Step 3. Update Dataphor to the latest version

If, despite the association of the Dataphor program with the Dataphor Data 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 Dataphor developers website or update the program from the application.

Step 4. Check for the following problems with the D4C file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the D4C file. The only repair option is to download the file again.
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. The scan should cover the entire computer, not only the D4C file that we want to open. Sometimes virus-infected D4C files cannot be recovered, so make a backup in advance.
Older version of D4C file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair D4C file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted D4C 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. It is best to move D4C to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file D4C to close. Some anti-virus or backup software may occupy the D4C file for a certain period of time. If this does not work either, restart the device.
