StandaloneFileBrowser can't be found

TriLib comes with a custom version of StandaloneFileBrowser (the original can be found here: https://github.com/gkngkc/UnityStandaloneFileBrowser)

It is an optional package, and if you don't want to use it, you can import only the "TriLibCore" (and the folder from your rendering pipeline, if you're using anything other than the Standard rendering pipeline) folder from the TriLib package.

Sometimes when building/running your application, you may get a message saying "StandaloneFileBrowser" can't be found or something similar. Generally, this happens because the appropriate StandaloneFileBrowser plugin hasn't been included in your build project.

To make sure StandaloneFileBrowser is included in your build project, head to the "Assets/TriLib/TriLibStandaloneFileBrowser/Plugins" directory and look for the plugin file according to the platform you will deploy to. In this case, I'm selecting the "x64" StandaloneFileBrowser plugin inside the "Windows" folder, as I will deploy my application to Windows x64 devices:

You can then select the appropriate architecture you want the selected plugin to be used:

This should fix the "StandaloneFileBrowser can't be found" type of issue.
