how to move the textmate file explorer to the right side?

For Textmate 2 (released long after this question was answered) the accepted answer doesn't appear to work anymore. This is what did it for me:

To change it to the right on OSX, open up your terminal and run the command:

defaults write com.macromates.TextMate.preview fileBrowserPlacement right

To change it to the left:

defaults write com.macromates.TextMate.preview fileBrowserPlacement left
