Do you know of a way to enter a file directly from the MXD extension QGIS? Is this possible? How about MapPackage files? I do not have access to the ArcMap software. Best Regards.
Importing MXD files into QGIS is not possible because MXD is proprietary ESRI-only formats, with no public specifications allowing their use.
North Road is actually developping a QGIS plugin for converting MXD and LYR files into QGIS compatible format. They already have created a plugin - SLYR - to convert .style ESRI files to QGIS format, and they want to develop it more to make it compatible with MXD and LYR formats. Please read this for more informations.
If you own an ESRI licence, you can try to use the arcgis2qgs toolbox to convert MXD to QGS files.
