Hello,
I've recently upgraded to ArcGIS Desktop 10.3, but many of my colleagues are using 10.1 or 10.2. They've let me know of this error they get when they try to open any map .mxd I've worked on: "This map document was saved using a newer version of ArcGIS." Following the directions in the error message (see attached), I "Save A Copy" to the older file format and they are able to open the file OK. However, I've noticed that if I open the legacy copy and save it, it reverts back to the 10.3 file format.
I've got two questions related to this process:
1) Is it possible to identify which version of ArcGIS a file is saved in? I don't see it in the map document properties when viewed from ArcCatalog.
2) Is it possible to set ArcMap 10.3 to automatically or by default save .mxd files in an older version, such as 10.2?
I'm new to ArcGIS, so forgive me if this is an issue that has a long history over the many version changes in the past.
Thanks,
Ben
