Note the File Type
Other programs may be able to open your FM3 file, depending on the type of file it is. You can find the file type listed in the file’s properties. On a Windows PC, right-click the file, click "Properties", then look under “Type of File.” On a Mac computer, right-click the file, click “More Info,” then look under “Kind”.
Tip: If it’s the FM3 file extension, it probably falls under the Settings Files type, so any program used for Settings Files should open your FM3 file.

Use a Universal File Viewer
When all else fails, a universal file viewer is the best way to open a FM3 file. Programs like File Magic (Download) can open many different types of files, depending on the format. Although, some files may not be compatible with these programs. If your FM3 file isn’t compatible, it will only open in binary format.
