The .mxd file in ArcGIS does not store the actual data (like layers and tables) within it. Instead, it saves references or paths to where the data is stored on the disk, along with other settings and properties of the map document. This means that the .mxd file contains information about the data's location and how it is organized and displayed, but not the data itself.
