your program works pretty well, here are some things that I noticed.
clicking on the c drive for the first time doesnt take you to c root. you have to click on another drive and then back for it to work.
the camera roll function keeps rolling until you reset the camera. maybe get it to snap back to zero after mouseup.
the zoom distance isn't great enough for all models, maybe make zoom out infinite so you can see bigger models. eg buildings from fpsc packs.
I also cannot get the view animation feature to work.
maybe look into using the windows file loader found in gogas free dbp plugin.
That way you can use your library links to easily find your media rather than having to get there through the root drive. although the file loader you do have is well made and generally functions well.
good job, well done.
