What is a .odi file?
A .odi file is an ODI image. Its registered MIME type is application/vnd.oasis.opendocument.image, which places it in the application or document family of formats.
ODI stands for OpenDocument Image.
Technically it is a specialised form of application/zip (the .zip format), so tools that understand that format can often read at least part of it.
ODI is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.
Files of this type usually begin with the bytes 50 4B 03 04. That signature is how programs recognise the format even when the extension is wrong or missing.
