Mark-the-app-addict!! ,

Great Application

I am a university student and I've used this application to preload all my lecture and tutorial slides and arrange them into folders for each subject and week!!!
Only problem is some slides won't load, when the power points are pptm or documents are docm they won't work!!!
And some slides load but some words can't be seen or don't fit on slides!!
