Currently, out team is in the transition of switching between ArcGIS Desktop and ArcGIS Pro. In the past, we would store .mxd files in a directory named MXD. Now that ArcGIS Pro produces several new file names (.mapx, .pagx, .aprx), we are thinking about storing all these files in a single directory as well. However, the name MXD doesn't really fit anymore! We are curious how others are managing their directory structure with these new files. Thanks for any suggestions!
