This tab displays the file content of the currently edited stylesheet's theme folder and allows it to be managed. The theme folder of a stylesheet is always located under the App_Themes directory and its name is the same as the code name of the stylesheet it belongs to. It usually contains files used by the stylesheet, such as images, skin files and other resources.
Detailed information about the actions available on this tab can be found in the File system dialog help topic.
Please note, only file formats commonly required by CSS stylesheets are displayed here. This includes the following: .css, .skin, .gif, .png, .bmp, .jpg
