There is only one file type that uses the .WEBDOC extension:
Box.net Web Document
Online document created using Zoho Editor, a Web browser application used to edit documents for the Box.net file sharing service; saves the document in a proprietary Box.net format that is only editable with the online Zoho Editor; can be viewed with the Box.net offline Box Sync application.
Even though Box.net supports the proprietary WEBDOC format, users commonly use other document formats such as .DOCX, .PPTX, and .RTF.
