A page, web, frameset, or cascading style sheet template directory must use the extension .tem, such as \Sample.tem to be recognized by FrontPage. Depending on its content, this directory must be placed either in the FrontPage webs, pages, frames, or cascading style sheet directory. These template directories are located in the directory structure directly beneath the FrontPage root directory. The sample program "fproot" demonstrates how you can determine where custom templates of a given type should be installed for any version of FrontPage.
