There is a way to point your your documenst, pictures , videos to any drive, windows will move the files there and future files will be saved there. While this can be done I do not reccomend it with removable USB flash drives ves permanently. You can temporarily move the file for update then maybe move them back. If you are low on space consider a hard-disk upgrade. ?? A good time to consider an SSD it will speed up most modern computers as well as extend operating time on battery.
