Formatting a turtle/computer

I accidentally overrode the "programs" program with one of my own. I can no longer see all of my programs and everything important is backed up on drives. It would be really simple if I could just format it. Is there a way to entirely format it, even though it has a label already? Thank you.

Do you mean erase everything on the turtle?

Yes I do, and after a little playing around I was able to just clear the label then pick up the turtle.
For anyone who has a similar problem in the future I used "
label clear
" to get rid of the label. It was a simple fix that I wish I had just tried before making a post :P/>.

A easier way to do it is this:

for k,v in pairs(fs.list("/")) do
  if not fs.isReadOnly(v) then
    fs.delete(v)
  end
end

For future reference, you didn't actually override it, since it's in ROM. You could just have done rm /programs and all would have been well again.
