View source for Special Folder Names in your Assets Folder

== "Plugins" ==
The "Plugins" folder is where you must put any native plugins, which you want to be accessible by your scripts. They will also be automatically included in your build. Take note that this folder may not be in any subfolder (it has to reside within the top-level Assets folder).

In Windows, native plugins exist as .dll files, in Mac OS X, they are .bundle files, and in Linux, they are .so files.

Like the Standard Assets folder, any scripts in here are compiled earlier, allowing them to be accessed by other scripts (of any language) that are outside the Plugins folder.


=== "Plugins/x86" ===
If you are building for 32-bit or a universal (both 32 and 64 bit) platform, and if this subfolder exists, any native plugin files in this folder will automatically be included in your build. If this folder does not exist, Unity will look for native plugins inside the parent Plugins folder instead.


=== "Plugins/x86_64" ===
If you are building for 64-bit or a universal (both 32 and 64 bit) platform, and if this subfolder exists, any native plugin files in this folder will automatically be included in your build. If this folder does not exist, Unity will look for native plugins inside the parent Plugins folder instead.


If you are making a universal build, it's recommended you make both the x86 and x86_64 subfolders. Then have the 32-bit and 64-bit versions of your native plugins in the proper subfolder correspondingly.


=== "Plugins/Android" ===
Place here any Java .jar files you want included in your Android project, used for Java-based plugins. Any .so file (when having Android NDK-based plugins) will also be included. See http://docs.unity3d.com/Documentation/Manual/PluginsForAndroid.html


=== "Plugins/iOS" ===
A limited, simple way to automatically add (as symbolic links) any .a, .m, .mm, .c, or .cpp files into the generated Xcode project. See http://docs.unity3d.com/Documentation/Manual/PluginsForIOS.html

If you need more control how to automatically add files to the Xcode project, you should make use of the PostprocessBuildPlayer feature. Doing so does not require you to place such files in the Plugins/iOS folder. See http://docs.unity3d.com/Documentation/Manual/BuildPlayerPipeline.html
