HFXS files won't open
I was having issues with my notebook drive "C", a 256 GB SSD so I backed up my hfxs files to an external HDD, replaced my old SSD with a new 1TB, copied my hfxs files back onto my new SSD, installed HitFilm Express, but when I try to open the hfxs files, I get a message/window that there is no program associated to that extension and that I have to choose a program to open them. I tried HitFilm express program to no avail. What am I missing? Or what is missing? Please help!
