Maybe another tip:
I run Condor on a laptop with only 2 sceneries in its Landscapes directory.
The default Slovenia scenery plus
the scenery I will be using on my next flight.
All other sceneries are kept in a separate Landscapes "Warehouse".
The main reason for that is my Antivirus package, that doesn't allow me to omit a folder/directory from a regular antivirus scan on system-files.
Running Windows 7, Condor was installed in the c:\program files(x86\ folder, which Windows 7 considers a system file.
Installing sceneries into the default folder structure causes regular AV-scans to last forever.
Which, of course, is unacceptable on a laptop.
The separate Landscapes Warehouse is the one that contains all scanned sceneries and is omited from regular scans. The Landscape files never change.
Moving an entire scenery folder from the Warehouse to the Condor\landscapes folder (left mouse drag&drop) only takes a couple of seconds.
