Why 7Zip instead of WinRar? Because you will find many things nowadays are packaged as '_.7z' format.

unlike JSGME, you can update or make changes to any addons at any time, without needing to disabling & enabling them.ħZip can be found at, of course we want the 64-bit version.

you can store multiple profiles of different mod combination setup, switching profile is instant - because as mentioned above, managing the mod list do not causes any actual physical file movements Remember: a lot of these mods WILL NOT work together, so youll have to set prioritys and whatnot.

It also tag any mods which got overwritten completely as 'redundant' with a special icon.

MO2 shows you exactly which mod conflict with which other mods, providing a detailed list of every single file which is affected.

Because mods are linked with the game without any physical file movements, this means disabling & enabling mods, re-organizing mod order are INSTANT without any waiting or loading. Im not sure if this is relevant, but whe. I have double-checked and the skse link uses C:\Program Files (x86)\Steam\steamapps\common\Skyrim\skseloader.exe as the Binary entry.

Unlike other applications like JSGME which have two copies of every mods (one under it's care, one copied into game folder), MO2 only stores one copy of installed mod - and 'magically' link it with the game upon launching the game, without physically moving anything. I have the skyrim script extender loaded into the mod organizer but it wont run it.

no duplicate mod files in different directories.

do not modify the original game files, instead it load mod files on top of the game upon launching the game, by utilizing something called 'virtual file system'.
