To add on top of that... Some of the big companies are on the look out for those using their files as base files. So obtaining the 3rd party tools and reading out a deleting file can be a little sketchy being the big tuning companies are on the look out for it and noting those who do.
Remember, the big companies put their signatures into the hex and all they have to do is search that string out of anyone's read file and find their signature in it.
Just FWIW.
