When trying to export a map as an MPK, ArcMap gets stuck at "Preparing Data (Folder Size 0KB)". I have tried a couple different MXDs and they all have this problem.
I am working off a server with a not-so-great connection, but the connection isn't that bad. Any thoughts on what could be causing this? There are only 2 layers, 1 raster and 1 vector. Vector is v small, raster is about 1.7 GB. Maybe it is just that the files are too big, but I've let it run for twenty minutes now and it has not changed...
Did you ever find a solution? I have the same problem with ArcGIS 10.8.
