The file with .SHTM extension is the Web Files type. SHTM files belong to HTML File Containing Server Side Directives by Microsoft. This file extension is supported by 2 operating systems – Mac OS and Windows.
SHTM is HTML Server Side Include File. It is the server side scripting language SSI (Server Side Includes) – directives placed in HTML pages. These are evaluated on the server as the pages are served. They let you dynamically add content to an existing page.
The .shtm file extension stores html page with SSI code. SHTM files are HTML documents with SSI code to be processed by the server before sending the page to the browser.
Common programs that open SHTM files are Adobe Creative Suite and Internet Explorer. If you can’t open a .shtm file, Windows doesn’t recognize the extension. You need to update the application you use to open these files.
