StarOffice Document Template (.stw)
The STW file extension is associated with StarOffice, an office suite developed by Sun Microsystems and later acquired by Oracle. These files serve as document templates, enabling the creation of new documents with consistent formatting and layout, thus saving users time and effort. Although the STW format was replaced by the ODT format in Apache OpenOffice, it remains relevant for users of older software versions and can still be accessed with compatible programs.
