         <source>Mod Organizer uses an API provided by the Nexus to provide features like checking for updates and downloading files. Unfortunately this API has not been made available officially to third party tools like MO so we have to impersonate the Nexus Mod Manager to be allowed in.
 On top of this Nexus has used the client identification to lock out outdated versions of NMM to force users to update. This means that MO also needs to impersonate the new version of NMM even if MO doesn&apos;t need an update. Therefore you can configure the version to identify as here.
 Please note that MO does identify itself as MO to the webserver, it&apos;s not lying about what it is. It is merely adding a &quot;compatible&quot; NMM version to the user agent.

         <source>&lt;html&gt;&lt;head/&gt;&lt;body&gt;&lt;p&gt;By default, MO will parse archive files (BSA, BA2) to calculate conflicts between the contents of the archive files and other loose files. This process has a noticeable cost in performance.&lt;/p&gt;&lt;p&gt;This feature should not be confused with the archive management feature offered by MO1. MO2 will only show conflicts with archives and will NOT load them into the game or program.&lt;/p&gt;&lt;p&gt;If you disable this feature, MO will only display conflicts between loose files.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</source>
