could someone explain this item. my current data says 1.9 terrabyte which is my ssd 2tb almost.
i have had x-plane 11 with orbx installed but that one have I skipped.
my c drive shows 1.7 availeble from the 2tb so msfs only uses 300 gb. why there is in msfs 1.9 tb consumption is not clear for me.
You mean the network traffic data ? It’s what you donwloaded while your flights and it is not stored on your discs. Exception is the rolling cache, which hold a specific amount of these downloaded data so that you not need to redownload this again in case you fly over same area.
