Know to Set File Association via Group Policy


Recently after installing FAX Server on our site, we are having some problem with opening received FAX file from user desktop. FAX files are .G3N/.G3F/.CTLof which .G3N and .G3F file can be opened in Windows Image Viewer and .CTLfile can be opened in Notepad.
But the problem is, users have to make it their own, or we have to do it manually on all workstation across all branches. But it’s almost impossible to do so, so we have to think about some global solution.

Now we start working on creation a Group policy with which we can easily define default file association for those files and finally we created one.
FileAssociation.ADM
