How to open FOS file?
The main problem with Fallout 3 Saved Game is that the FOS file is incorrectly associated with programs. This is manifested by the fact that FOS 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 FOS 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 Fallout 3
The first step is to check if the computer has the Fallout 3 program installed. This can be achieved by typing Fallout 3 into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support FOS files.
Programs to open FOS file
Remember to download programs supporting FOS files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Fallout 3 with FOS files
If the application is or has been freshly installed, but the FOS file still does not use the Fallout 3 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. 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 FOS file with the Fallout 3 program.
Step 3. Update Fallout 3 to the latest version
The fault may also lie with the Fallout 3 program, it is possible that Fallout 3 Saved Game requires a newer version of the program. This can be done using the application (if it provides such options) or from the Bethesda Softworks LLC website and install the latest version.
Step 4. Check for the following problems with the FOS file
If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:
The FOS file may be unusually small compared to the original file. This is most often caused by a problem while downloading the FOS file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our FOS file. Sometimes virus-infected FOS files cannot be recovered, so make a backup in advance.
Older version of FOS 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 this. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair FOS file corruption. The easiest way to restore the file is from a backup or by contacting Bethesda Softworks, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted FOS 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move FOS to a different directory.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file FOS to close. 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.
