Here’s a quick OS X tip – but only works if you’re using OS X 10.6 (Snow Leopard). You’ve always been able to drag items from the Trash to your Desktop (or any other folder) if you decide not to delete them. Now you can move some (or all) files from your Trash back to their original location on your Mac.
To do so, select the items you want to move back to their original locations from the Trash, then right-click (or ctrl-click if you have a single-button mouse) and select Put Back.
Now all the files you selected will be relocated back to their previous locations. No need to manually move files around one by one anymore :)
