I have created a package file. I want to modify a copy of that packaged file but preserve the original. If I open it directly and modify it, then both package files get modified, the original and the copy.
- They both unpack with the same name to the same folder.
- If I erase the folder that is automatically created then all changes are erased from all package files.
- If I use the extract tool then a new .mxd file is created and the problem is solved. They both alter only their specific package file.
Why is ArcGIS behaving like this? I am curious because I am learning to use it.
