Vortex doesn't have an 'export' LO option, so I will explain how to access the FNV's 'plugins.txt'. Mod Organizer (MO for short) users will not have any pictures because I never used MO and so I can't really get pics, sorry. I will show you how you can export your Load Order (LO for short) easily using Fallout Mod Manager (FOMM for short), Mod Organizer 2 (MO2) and Nexus Mod Manager (NMM for short).
