At my place of work, we operate on several different versions of ArcGIS. A coworker is trying to share an .mxd with me, that she prepared using v10.5, and is using Save as Copy for my v10.3. The file contains several .shp as well as .csv that have been joined to the .shp, as well as some that hasn't. However, when I open it on my computer, only the .shp-files remain in the document, and the .csv-files are gone. Why does it delete all the .csv from my .mxd and how can I make sure all the added data is transferred between versions, so that I can see her work?
