Today's mishap:
Involving
My 16gb Partition (with windows 7)
Borderlands save game files!
The Story
I was trying to free up some space as the partition only had 1gb left. So I browsed to the "My Games" (for those who don't know, this is where most of the save game files can be found for your games) folder found in "Documents" and looked for anything particularly big. I saw UT3 which I hadn't been playing in a while and deleting it was a good idea. I right-clicked it and it said it took up about 1.6gb of space. Hastily I shift-deleted the folder and was finally glad I recovered some space.
The Mishap
Funny thing was, was when I right clicked. I actually selected the entire "My Games" folder instead of "UT3" and when I "Shift-Deleted", well... that was the mishap.
Result
-Lost 2 characters
(Hunter) Lv.41 (Was in the underdome)
(Soldier) Lv.39 (Was at Jakobs Cove)
(tl;dr)
Wanted to free space > went to "My Games" folder that contained save game files > deleted it instead of another folder > oops.
Sorry to hear, though.
