Step 2. Create association of Office SharePoint Designer with SPDESIGNUNKNOWN files

If, despite the installed application, the SPDESIGNUNKNOWN file does not start in the Office SharePoint Designer application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. 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. The "always use the selected program ..." field will set the Office SharePoint Designer application as the default for handling the SPDESIGNUNKNOWN file.

Step 3. Update Office SharePoint Designer to the latest version

If, however, after binding Office SharePoint Designer with SharePoint Designer there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The SPDESIGNUNKNOWN file may be unusually small compared to the original file. This is most often caused by a problem while downloading the SPDESIGNUNKNOWN file. 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. The scan should cover the entire computer, not only the SPDESIGNUNKNOWN file that we want to open. Sometimes virus-infected SPDESIGNUNKNOWN files cannot be recovered, so make a backup in advance.
Older version of SPDESIGNUNKNOWN 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 the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular SPDESIGNUNKNOWN file corruption. The easiest way to restore the file is from a backup or by contacting Microsoft Corporation, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted SPDESIGNUNKNOWN 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 of the system directories are excluded from modification. The problem is only writing to the file, not reading it. If possible, you can try to move the SPDESIGNUNKNOWN file to another location.
This problem usually affects more complex files. In this case, the SPDESIGNUNKNOWN file is blocked by the first application to open it. Closing other programs should help. Sometimes you have to wait for the session to the file SPDESIGNUNKNOWN to close. Some anti-virus or backup software may occupy the SPDESIGNUNKNOWN file for a certain period of time. If the problem persists, restart the machine.
