So had a problem where a 16GB ISO was damaged(likely my own fault using standard windows copy dialog instead of proper copy tool like robocopy with verification turned on).

It took several hours but i managed to restore the ISO(basicly i rebuilt the damaged parts and recompiled).Namely some .rar archives inside it were unreadable but the ISO itself was readable.

So im wondering how can i further protect something like this from happening again?.Obviously proper copy tool but mayble something else?.Perhaps set as "read only" could help?.I generally don't move these files a lot and if i need to acces them then it's only for opening/extracting.
