Earlier today I decided to polish my external harddisk, on which I kept every important things from my 3 years of being a computer programmer: all my past programming projects, web designs, mp3, ebooks, videos, writings, games...
Windows screwed up my hard drive; I was deleting files from multiple folders at the same time.

Don't do it please. I'm at the starting point again. But why would my intention to polish my "knowledge storage" end up like this, forcing me to start everything again?
Some of these projects/writings/creations would cheer me up when I'm lost...
