Windows only: Free utility Copy Path adds a new entry to your right-click context menu that lets you quickly copy the full path to any file with two clicks of your mouse. Why would you want something like this?
I can think of plenty of reasons this functionality would come in handy, but we mentioned the most useful back when we covered ClipPath, a similar tool:
[L]et's say you're looking at a file sitting happily inside its folder, but you want to send it to a friend with Gmail. In order to do so, you'd have to browse through your whole file system to find the file from your browser, even though you were already staring at the file in the first place.
With Copy Path installed, all you've got to do is right-click the file you want to upload, copy the path, and paste it into the attachment text box. The same holds true for uploading a file to any web site, naturally. It's a small difference, to be sure, but it'll definitely save time, and nothing's more irritating than navigating to a file using your browser's upload dialog when you're already staring at the file in Explorer.
Copy Path is a free download, Windows only.
