I used to have this set to open the file in GIMP but I've reinstalled windows and cant for the life of me remember how to do it.

I tried this "C:\Program Files\GIMP 2\bin\gimp-2.10.exe %1" but it doesn't work properly.

Can anyone help?

"C:\Program Files\GIMP 2\bin\gimp-2.10.exe" %1

C:\Program Files\GIMP 2\bin\gimp-2.10.exe "%1"

You'll want quotes around the exe path if it contains spaces. (It may work without, by luck, but only until something creates a C:\Program folder and breaks it.)

Whether you also need another pair of quotes around the %1 depends on the program you are running, but you usually do.
