What is an SXI file?
Presentation originally created by StarOffice Impress, a program used for creating slide shows; generally follows a slide layout template and contains a title slide followed by content slides; supports audio, video, and transition effects.
SXI files were used by StarOffice version 5 and Apache OpenOffice version 1 (previously part of OpenOffice.org). Earlier versions of StarOffice used .SDP files for presentations. Later versions of Apache OpenOffice use the .ODP format for presentations.
