Sets the folder suffix for the specified presentation to the default suffix for the language support you have selected or installed.
expression.UseDefaultFolderSuffix
expression An expression that returns a WebOptions object.
Remarks
Microsoft PowerPoint uses the folder suffix when you save or publish a complete or partial presentation as a Web page, use long file names, and choose to save supporting files in a separate folder (that is, if the UseLongFileNames and OrganizeInFolder properties are set to True).
The suffix appears in the folder name after the presentation name. For example, if the presentation is called "Pres1" and the language is English, the folder name is Pres1_files. The folder suffixes for each language are listed in the FolderSuffix property topic.
Example
This example sets the folder suffix for the active presentation to the default suffix.
