Best way to delete images on Extreme IV

Just wondering if it is best to delete files when finished copying by using camera delete or from desktop clearing all files or re formatting disc?
It is a 4 gb

best to format the card in your camera

So don’t delete individual files just format once files are copied?

Also if you do delete individually should your format from time to time to get card clean>>


deleting individual files is fine but yes you should periodically format the card
