How to open SSFN file?

The main problem with Steam Guard Data Format is that the SSFN file is incorrectly associated with programs. This causes the file SSFN to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the SSFN 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 Steam

An often overlooked issue is to make sure that Steam is installed on the computer. This can be achieved by typing Steam 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 SSFN with Steam. Below you will find a list of applications that support SSFN files.

Programs to open SSFN file

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

Step 2. Create association of Steam with SSFN files

If the application is or has been freshly installed, but the SSFN file still does not use the Steam program, it means no association. It is most convenient to call the context menu with the right mouse button and select 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. 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 Steam application as the default for handling the SSFN file.

Step 3. Update Steam to the latest version

The fault may also lie with the Steam program, it is possible that Steam Guard Data Format requires a newer version of the program. In this case, use the Valve Corporation website or update the program from the application.

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

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the SSFN file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the SSFN file that we want to open. As a result of the scan, sometimes it is not possible to recover SSFN files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the SSFN files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair SSFN file corruption. The easiest way is to restore the file from a backup, if there is one, or contact
When reading, a message appears that the file was encrypted or corrupted. The encrypted file SSFN 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.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move SSFN to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes you have to wait for the session to the file SSFN to close. 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.
