If players are going to switch between CF and ANY other mod, the only way I have been able to do it with FLMM is to use the Tools/Restore Backups function. Use the buttons on the FLMM window to do this; "restore" puts FL back to default vanilla, and can take up to 10 min's with a mod as large as CF. Once the backups are restored, a notice window pops up to announce how many files and folders have been changed; click OK and you are ready to activate a different mod (if you must !). [12]
