ODI magic bytes (.odi)
.odi file signature: 50 4B | application/vnd.oasis.opendocument.image
Category: Images
OpenDocument Image (ODI) is an XML-based file format in the OpenDocument family, standardized and maintained by OASIS. It is used for storing image-oriented content and may be handled by office suites and document editors that support OpenDocument formats. As a standards-based format, it is generally safe to open, though files from untrusted sources should still be treated cautiously because they may reference external content or contain complex embedded objects.
