Using 21st software to keep students organize

I currently work with several disabled students who are challenged with being organized. I’m constantly researching ways that will permit my students to be better equipped in having their notes and keeping up with their assignments. Some of my students use flash drives to save their work and others have to save all work done on the computer as they have a hard time carrying a book bag around all day. So I will be looking for ways to help SWD students to stay organize .
