Just a quickie.
One day I had all my settings for Arma 3 reset, all my awesome experiment missions files wiped clean and the whole folder with Arma tools disappeared. Yes you guessed it, I accidentally dragged and dropped them into another folder. Once I have realised what had happened, I thought there must be a setting on WIN7 to activate some sort of prompt on drag and drop event. Guess what, no such thing and on Microsoft website forum a Microsoft representative was less than useless about it.
One of the posters on that forum thread made a simple .dll and installer to alert you on Drag&Drop. I downloaded it and it works great. Here is the website in case you need it: http://broken-e.com/dragdropconfirm/
