Um.......,,,,yes, I do know the difference between a megabyte and a gigabyte (but I appreciate your explanation and the spirit in which it was given.) My secondary data drive is 500 G's. (I also have another external backup drive I just got which is 2TB.) I selected all the winRAR files marked "backup," and they totaled 365 G's. Which is staggering, I know. That was why I asked the question: why on earth would I need that kind of space tied up in (supposedly zipped) backup?
WinRAR is something new to me, I don't know why it's there, and I don't know if I need it. I am totally backed four ways to Sunday......on two external drives, online with Mozybackup, RAID, etc, etc. I don't think I need anything else, certainly not a program that ties up hundreds of Gigabytes.
I'm inclined to shut off its backup at the very least.....
