Disk fragmentation is an old problem that has affected every operating system throughout history. File fragmentation occurs when a single file isn’t located in the same physical location on the disk, but is scattered around. OS X does a great job at minimizing file fragmentation by rewriting files in contiguous space when a file is opened, is under 20MB and contains more than eight fragments. This works quite well to prevent heavy file fragmentation, but what it doesn’t prevent is free space fragmentation.

The most annoying thing with running windows in a Parallels virtual machine, is that the default key mappings for navigating text is different between windows and OS X:
Windows:
- Go to end of line = End
- Go to start of line = Home
- Go to next word = control-right arrow
- Go to previous word = control-left arrow
OS X:
- Go to end of line = command-right arrow
- Go to start of line = comand-left arrow
- Go to next word = option(alt)-right arrow
- Go to previous word = option(alt)-left arrow
Parallels by default remaps the text copy, cut & paste from command-c to control-c, command-v to control-v etc. Why oh Why didn’t it do this for text navigation I bemoaned over and over, frustratingly trying to remember which OS I was using and switching to the right one.
Then, today, I had a moment of clarity. It was so obvious. I felt stupid for not looking for it before. Behold the screen shot below and now I am calm and relaxed with a unified text navigation scheme.
