ThinkFree Viewer 1.1
ThinkFree Viewer Extensions allow you to view documents on other web sites by simply
right clicking a document link, then choosing the appropriate ThinkFree viewer application
(Write for DOC files, Calc for XLS files, or Show for PPT files). For Firefox users, the menu is
context sensitive so the correct viewer application will automatically appear. For example,
in the scenario below, this Firefox user is opening a presentation file. The viewer extension
automatically shows the option to "View with ThinkFree Show."

File types supported are: DOC, RTF, TXT, XLS, CSV, PPT, and PPS.
