SERIOUS HELP NEEDED: How To Store Files So They Can't Altered?
Hey everyone, I'm sorry to be creating a thread about this, but this is a super worrying problem for me.
This is my problem:
I want to backup all of my work files and personal files and ebook files which are in the format of .PDF files. I was going to use an external USB HDD, BUT it seems so easy for someone to just open up a .PDF and just make slight changes to it like removing text or altering the text slightly so that the information is changed without me knowing it.
The best idea I had was that I could use a non-rewritable disc like a DVD-R to store the files.
I'd be VERY grateful for any help!
