What is an SXI file?

The SXI format is the native presentation file type for OpenOffice.org Impress, the predecessor to the modern OpenDocument Presentation (ODP) standard. Based on the StarOffice XML format, SXI files utilize ZIP compression to bundle XML definition files (content.xml, styles.xml) and binary media assets. It was the default format for the OpenOffice suite (versions 1.0 through 2.0) prior to the standardization of the OASIS OpenDocument Format (ODF) in 2005.

How to open an SXI file

Apache OpenOffice Impress and LibreOffice Impress provide the most robust native support for opening and converting legacy SXI files. Microsoft PowerPoint can open SXI files if the appropriate ODF converters are installed, though formatting discrepancies often occur. Google Slides supports importing SXI files for viewing and conversion to modern web-friendly formats.

What is a POTM file?

The POTM format is a macro-enabled presentation template introduced with Microsoft Office 2007, adhering to the Office Open XML (OOXML) standard. It utilizes ZIP compression to organize XML components but, unlike standard POTX files, allows the storage of Visual Basic for Applications (VBA) code within a vbaProject.bin part. This distinction enables the automation of tasks and custom scripting within the template structure.

How to open a POTM file

Opening POTM files requires software capable of executing or suppressing VBA macros securely. Microsoft PowerPoint is the primary application for Windows and macOS. While LibreOffice Impress and WPS Office can open the slide content, macro execution may be restricted or unsupported due to differences in the scripting backend compared to the Microsoft VBA engine.
