I accidentally overwrote a directory with another directory a few days ago. The files that were lost were from libraries I had installed. None of my source code or documents were lost (I back them up). But I did not know how to undo what I’d done, so I decided to back up a few more items and start from scratch.
So, I didn’t need any third-party partitioner.
For the text editor, I installed TextMate. I’m liking it so far, and expect that I’ll be buying it in a couple of days. Thank you for the recommendation.
