|How about doing the intelligent thing and backing those files up. What if the hard drive craps out instead of your kids messing with the files. There are many things that can go wrong. |
You can mark all the files to be read only or you can use what Windows has provided for you and make a separate profile with log-in for each user. Then they wouldn't have access to the files. Still could throw a disk in and reformat the drive though, I suppose.
I hope you get the real point of my sarcasm?
You should always maintain at least TWO copies of any files you wish to keep. There are many method to accomplish that with pros and cons for each.
One thing is sure. If you don't have at least a second copy you will eventually lose the data.
Buy an external hard drive that already has backup software included and use it.
In the case of, irreplaceable at any cost, items like photos I recommend burning them to optical media DVDR is cheap if bought in bulk and is very safe. Plus once a disk is created it is really fast, cheap and easy to duplicate for even more safety.
