Some non-Yahoo! Widgets could use a little help from extra files, like a ReadMe, installation instructions or a Software License Agreement. A third party support files folder—for example, My Documents\My Widgets\iTunes Companion 5.5.1—is where a compression program can extract these extra files from a zip file downloaded by the Yahoo! Widget Gallery Widget along with the Widget program itself.

Once you open the Widget, Yahoo! Widgets moves the Widget program into My Documents\My Widgets and preserves the folder, keeping, for example, iTunes Companion 5.5.1 and the files in it.
