Class:ReflectionMetadataClasses

The ReflectionMetadataClasses class represents a container for objects. It inherits from.

What is Reflection Metadata?
The Reflection Metadata is a special XML file that can be found in Roblox Studio's directory folder. It stores configurable information about classes.

To be more precise, it controls the following:
 * The visibility of objects in the Explorer window
 * The icons of objects in the Explorer window and Advanced Objects window.
 * The visibility and summary of classes & members in the Object Browser window.

Locating the Reflection Metadata
As stated earlier, the Reflection Metadata is located in Roblox Studio's directory folder.

To find this folder, you'll want to find a shortcut to Roblox Studio on your desktop. Once you find it, right click on it and press Open File Location. In this folder, you should see a file called "ReflectionMetadata.xml".

If the file is only labeled as "ReflectionMetadata" with no extension, you may want to change your settings.

Importing the Reflection Metadata
Just a disclaimer before you start editing: You need to be very careful. If you incorrectly edit the ReflectionMetadata, it can cause the Explorer to stop working, and it could potentially crash Roblox Studio. With that said, lets begin!

While you could just crack open the .xml file and manually edit it from there, that's kind of a tedious process. Instead, lets actually insert the file as a model!
 * Right click on ReflectionMetadata.xml
 * Press Copy, and then paste it somewhere you can easily navigate to.
 * Rename the file to ReflectionMetadata.rbxmx
 * Go into Roblox Studio, and open a new place.
 * Right click on the Workspace  and press "Insert from File..."
 * Navigate to the ReflectionMetadata.rbxmx file, select it, and press Open.

You should now see two objects in the Workspace. When you open them, you'll find a ton of objects pertaining to classes, enums, members, and more!
