Yes you can. .bdp zapper does not work on my win10 pc. Instead you can do this : Using windows file explorer,find the desired install and open it. In the top right corner of the file explorer you will see a search function. Type .BDP and enter. It will search All .BDP's in the install and list them. Then select them ALL (using ctrl and "a" keys) and select delete. This takes very little time and once you get used to it ,very easy. You can be more targeted and open,let's say,the aircraft file and just do aircraft ,and so on... Give the install plenty of time loading again because it will have to rebuild all .bdp's . Hope this helps . Regards,Scott
