The Merge button typically should be chosen when installing optional files that are add-ons to the mod. It uses the 圎dit codebase as an API, and can be used with Skyrim, Oblivion, Fallout New Vegas, Fallout 3, and Merge Plugins can't detect MO2's file path even when I pointed it out for it. Edit - Also be sure to path the destination for your patch into the folder MO2 reads for mods.
After accepting and rejecting changes and resolving conflicts, the user is asked to confirm changes, but made to the target. In this step, you will be using a program called zMerge to reduce the overall ESP count.
Don't want to run it until I verify that file paths are set up correctly. I am new to skyrim, mo2, xedit, merge plugins, and zmerge.
