Programs to open FF file

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

Step 2. Create association of Call of Duty with FF files

If the application is or has been freshly installed, but the FF file still does not use the Call of Duty program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. 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 Call of Duty application as the default for handling the FF file.

Step 3. Update Call of Duty to the latest version

The fault may also lie with the Call of Duty program, it is possible that Call Of Duty 4 Fast Format requires a newer version of the program. This can be done using the application (if it provides such options) or from the Activision website and install the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the FF 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 virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file FF or the program directory. As a result of the scan, sometimes it is not possible to recover FF files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of FF 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.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular FF file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Activision
The program indicates that the file is encrypted or corrupted. The encrypted FF 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. While there is usually no problem reading such a file, it may not be possible to save it. Copying the FF file to another location will fix the problem.
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 FF to close. Some anti-virus or backup software may occupy the FF file for a certain period of time. If nothing helps, please reset the device.
