How do you delete everything possible?

Long story short, how would you create a disk to basically wipe a computer?

Try with this:

for _,file in ipairs(fs.list("/")) do
  if not fs.isReadOnly(file) then
    fs.delete(file)
  end
end

It's not tested, but it should delete every file and directory in the root directory, leaving only the rom folder (wich can't be deleted).

It worked.

Good to know, just don't use it for evil :)/>/>

Lol, i only needed one of those because i screwed up two computers. One was a virus, one was a attempt at creating a network that displays a log of computers startups and actions on one giant monitor.
