locked Keeping or Deleting old WSJT-x .wav files, unwanted WSJT .c2 Files. Benefits and Hazzards.

Mark W2OR

It might be beneficial for newbies to read on this (great) list serve the benefits and hazzards of deleting, or keeping, the relatively unused .wav and .c2 files in WSJT-x.  Other than the Sample lessons, perhaps someone could explain what they are, why they are kept on disc, how they are sometimes used, and how much disc space they can take up as the months pass by, using WSJT-X.  Thank you.   

p.s.  Ctrl+O opens the file location where one can observe the number and size of these files.
