I went from 8.1 to Windows 10; Some good, some not so good.  I want to put all of my data on a thumb drive which is mostly documents.  With 8.1 it was easy for me although I don' recall how I did it.

I need a step by step with 10.  Also, is it recommended to also save systems?  I  have a 32 GB TD but since I don't know how to find the size of my data, documents, or system, am stumped for now.  Merry Xmas and Semper Fi Ben
