Hello it's me again :-)

I have started to catalog my cards and place them into folders, all is going well apart from my media player BLC well no it plays them fine, but when I go into my video folder I just have a orange and white cones but I would like to see them in picture icons.

I go to the drop down menu and change it to icon sizes, the problem is when i go into another Video folder i have to do the same. Is there any way i can make it so all my video files are in thumbnail when I open each folder, it's getting very tedious having to do them one at a time ?

Thanks in advance
