A user at Stack Exchange asked an interesting question recently : how can you open a new Finder window in the same folder as the frontmost window? When you open a new Finder window (Command-N in the Finder), it opens to the folder you've set in the Finder's General preferences. There may be some situations when you want to duplicate the current window, such as when you're moving files around among sub-folders in a specific folder.
Another reader, Lauri Ranta, posted a simple AppleScript, that you can use together with a keyboard shortcut, to do just this. When you run the script, it creates a new window at the same location as the frontmost window. Here's the script:
tell application "Finder"
try
target of window 1
make new Finder window to result
on error
make new Finder window to home
end try
end tell
Save this as a script, and use any tool that can apply keyboard shortcuts to AppleScripts. Or save it as an application, drag it to the Finder window toolbar, and it'll be just a click away. (You can move the application to any location you want afterwards.)
