If you’ve ever uploaded a picture to Facebook or tried to attach a file to an email using the “add attachments” button, you know it can be a pain using the tiny pop-up file uploader window to navigate through your folder structure to the file you want. If you’re on a Mac (and some versions of Windows) you can make this process much quicker by dragging the file to the upload window.
The next time you want to upload a file, keep the folder it is in next to your browser window (or on the desktop). When the upload window appears, simply drag the file over top of it and drop. The upload window will automagically snap to the correct folder and highlight the file. All you have to do is click the upload button.
