As part of my job I use Solidworks 2013 3D CAD software. http://en.wikipedia.org/wiki/SolidWorks
I have a lot of Solidworks CAD files in various folders on my computer. When trying to access these folders using opus the lister takes a LONG time (5-10 seconds typically) to populate say 50 files when using Details mode. The time taken appears to bare a relationship to how many files are in the folder. At first I thought that this was because Opus was trying to draw an icon which represents the CAD model, so I turned on generic icons for all folders. This made no difference. Using windows explorer (in Details mode) does not exhibit this delay - it is pretty much instantaneous and I get the icon representing the cad model. What I have noticed is, if I use thumbnails view in opus the delay is less (typically 2-3 seconds) even though opus gives me a nice large thumbnail of the CAD model. Any thoughts/fixes for this slow behaviour in details mode? Could it be that in Details mode opus is trying to access some metadata that it doesn't in thumbnails mode?
