expression.UseDefaultFolderSuffix
expression An expression that returns a WebOptions object.
Remarks
Microsoft Excel uses the folder suffix when you save a document 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 document name. For example, if the document is called "Book1" and the language is English, the folder name is Book1_files. The available folder suffixes are listed in the FolderSuffix property topic.
Example
This example sets the folder suffix for the first workbook to the default suffix.
