The OpenType font format is supported by Mac OS X and Windows 2000 and later.

Template for creating formulas used by OpenOffice spreadsheets; allows cells within the spreadsheet to be automatically filled in based on formula calculations; formatted using the OASIS OpenDocument XML standard.

General interface format for creating tuft designs that can be processed by tufting machines; allows designs to be weaved into various textile products; contains information such as thread-up, yarn placement, and yarn tuft lengths.

The OTF file format is specified in a Windows .INI file-like structure.
