Just testing this some more.... Is it meant to work on sub folders too?  It doest appear to....

Hello!  I have now read all your posts and worked out how to locate and use an icon (I should have done this before posting my last message - my apologies). 

I have also run the application on a test folder and the results are very good!  I was initially very excited! Alas when I put a document in one of the empty directories it the icon doesn't automatically change back to full. I suspect I have to run the software again for this happen?

I was wondering if anyone has had any success running this software on say a daily basis so that the folders are constantly refreshed?  We are architects and have a huge amount of data kept in a standard folders structures set up for each project we are working on.  Being able to see which folders have content in them and which do not on a live basis would be incredibly useful for us.

If anyone has any thoughts on this it would be hugely appreciated.
