Here's a cool little Vista trick I just learned:
- Browse to a file.
- Hold down shift and right-click on the file.
- Select "Copy as Path"
The path for the file, include the filename, is now in your clipboard. You can paste it into any app. This is useful when sending a network file's path in mail or when trying to execute a file with command-line parameters (just paste into the run prompt or a cmd window).
