##### 43.3.3.6 Preventing duplicate file names based on paragraph formats

To ensure uniqueness of file names without using a prefix or suffix, you can have DITA2Go override a file name, by combining the two paragraph-based file-naming methods:

1. Add an element with a special @outputclass to enable creation of a file name other than from an existing paragraph, as described in §43.3.3.3 Creating special paragraph formats to name output files.
2. Use the FileName property in [HTMLParaStyles] for both the existing paragraph and the special paragraph formats. The file-name paragraph should follow (not precede) the heading paragraph; the last name specified wins.

For example:

    [HTMLParaStyles]
    Heading1 = Split Title FileName
    Splitname = FileName Delete
