I've made a little utility that enable and disable mods. With this software you can speed up the boot of rFactor without uninstall any mod and enable only what you use. In any time, you're able to switch on or off any mod.
The software must be installed and the first time you've to point at you rFactor installation folder.The utility don't move or delete any file, only rename .rfm files to .dis files for those mods you won't use. The software create and modify the KnownRFMs.ini file according to the choosed mods.
The software need the Framework 2 installed
