How to open D4 file?
The main problem with Dataphor Source is that the D4 file is incorrectly associated with programs. This is manifested by the fact that D4 files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the D4 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
An often overlooked issue is to make sure that Dataphor is installed on the computer. This can be achieved by typing Dataphor into the operating system search engine. 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 D4 files.
Programs to open D4 file
Remember to download programs supporting D4 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Dataphor with D4 files
If the application is or has been freshly installed, but the D4 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 displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Dataphor application as the default for handling the D4 file.
Step 3. Update Dataphor to the latest version
If, however, after binding Dataphor with Dataphor Source there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Dataphor developers page and install.
Step 4. Check for the following problems with the D4 file
The problem may also be with the file itself if the above steps don't work. The most common file problems are:
Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the D4 file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. 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. However, it is important to scan the entire system, not only the file D4 or the program directory. As a result of the scan, sometimes it is not possible to recover D4 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of D4 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. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair D4 file corruption. You can restore the file from a backup or use N/A help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted D4 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move D4 to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the D4 file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
