I have a map document file (.mxd) with a size of 0.3 MB. I also have two layer files (.lyr), containing large rasters. Together they are 16.2 MB. If I add the two layer files to my map document in ArcMap and save, it becomes 16.5 MB large.
This leads me to believe that all the data in the layer files are duplicated in the map document file. Is that so? If not, what causes the map document to swell? Is there any way to avoid this, since I want to keep the size of my map document low?
The layer files will be used in many map documents, and storing the rasters over and over again seems rather unnecessary.
