-<code>/home/tc/ -type f -size +1M | xargs ls -lhS</code>+If you run Tinycore from a USB drive, and normally change a lot of files when using it, it may be better to backup the home directory.
  
-For more information, see [[extension_for_settings|Make Extensions for Settings]].+If you use the USB drive as a repair and rescue tool, and don't change many files when using it, it may be better to use persistent home.
  
 +Ask the question: Is less written to the USB drive by saving files each time they are changed, or by saving everything in backup each time the computer is turned off?
  
-For more information, see+To set up persistent home, use the UUID, as discussed above.
