After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .FOS) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .FOS extension.

When choosing the software we can select the system to use this software every time.

Remember!
Using it for the first time it is good to check whether the .FOS file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .FOS extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .FOS extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .FOS file. Sometimes you have to repeat the operation several times.

Other instructions

If none of the programs listed by us to work with the .FOS file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.

In the vast majority of cases you will find the program dedicated to support the .FOS file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .FOS file) will be extended to the maximum.

It is also good to check

• if the .FOS file has no errors
• or if it has been copied (or downloaded by the browser) thoroughly

In such a case it is best to try to download the .FOS file again from the same source on the Internet (or look for another source). If you received the file from another person, ask this person to re-send it. However, if the file was copied from some media, repeat the copying operation.
