I do not know, how does the menu's option of Norton 360, "Erase" ("Borrar", in Spanish) work's.
There's a selection option. But, When I chose all the files I want to keep, just one of each, in my MacBook Air, It runs out of memory.
¿What do I have to do, to maintain the file and delete the rest?
I, already, download the Norton's Manual. But It sends me to the Norton Utilities Ultimate> toolbox > Recover -> Search Options.
