JPI File

A file with the .JPI extension is a file known as Jupiter Encrypted XML. It belongs to the Encoded Files category. This format is associated with Elfin Sp. z o.o..

The reliable way to open a .JPI file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.

We are still gathering the list of programs that open .JPI files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
