Files that contain the .pwi file extension are most commonly associated with the Microsoft Word word processing application for Windows Mobile devices, also known as Pocket Word.
PWI files contain word processing documents that have been created with the Pocket Word application. The PWI file format is similar to the DOC file format, but the PWI file format does not allow for the use of headers, footers, captions, footnotes or comments.
PWI files are used by hand-held and pocket computers, so they are less versatile than the full-featured DOC file format.
A user may be able to open a PWI file on their computer instead of their mobile device by syncing the device with their hard drive.
