I know that MXD contains information about layers, symbology and configuration of default tools. I have a few that are exceeding 50 MB and are starting to take a while to load up.
What are some of the main things that will increase a MXD's file size? Is there something specifically that dramatically increases the size?
Some of my ideas, that I have absolutely no proof of are:
- Complex layer symbology
- Multiple label classes per layer
- Definition queries
- Pulling layers from sources will long file paths (C:/MyFolder/Data/Data2/SubContainer/YouGetThePoint.shp)
- Scale Ranges for layers
- Arranging layers into groups
Do any of these ideas have any validity?
