.PMI File Extension

The pmi file extension is associated with the Pegasus Mail e-mail messaging service and client.

These file pairs reference actual mail folders, where messages are stored in a more compressed form. The former indexes the position of the message in the latter file.

How to open:

Use Pegasus Mail to work with *.pmi files.

How to convert:

As far as we know, this .pmi file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
