File-level administration is the last of the four levels of IIS administration. At this level you configure the properties of individual files within a Web or FTP site's home directory or other directories. For example, whereas a WWW service directory-level Properties dialog box has five tabs, the Properties dialog box for an individual Web page or other file has only four tabs: File, File Security, HTTP Headers, and Custom Errors (Figure 29-7).

Configuring file-level properties is basically the same as configuring directory-level properties, except that a single file can't have a default document specified for it as a directory can and you can't configure the following options at the file level: Directory Browsing, Index This Resource, and Enable Document Footer. Also, the location of the file can be either specified or redirected to a URL.
