What a MIE File Reveals: Serial, Owner and the File Inside

MIE, or Meta Information Encapsulation, is a container built to hold everything at once. It wraps a complete file alongside its metadata, keeps the original filename beside it, and can store the camera serial, the owner name, GPS, timestamps and free text in many languages. Any part of it may be compressed, so a tool that skips compressed sections reports the file as carrying nothing while a serial number sits inside.

What a .mie file reveals

The identity in a MIE file is unusually direct. The reference file published with the format carries a camera serial number, the owner name registered in the camera, the make and model, the software that wrote it, and a place recorded as a city, a state and a country. There is no guessing involved: MIE gives each value a named tag, so what the file says about its owner is stated rather than inferred.

It is also a wrapper. A MIE file holds a complete subfile, and it keeps that file's original name next to it. A filename names a folder, a job or a person as often as it names a document, and it survives here even when the wrapped file itself has been renamed. A thumbnail is stored the same way, as its own element beside the full image.

Free text is stored once per language, so one file can carry the same comment in a dozen locales, and each is separate content. The format allows both byte orders and permits any element or whole group to be zlib compressed, which is where readers usually give up. This scan decompresses those sections and decodes each string in the encoding the element declares, which is why the Japanese and Chinese comments read as text here rather than as mojibake.

Key fields

Camera Serial Number
The serial number of the camera body, tying every file from that camera to one device and often to its purchaser.
Owner Name
The name the camera owner registered in the camera itself, stored as a named tag rather than inferred from anything.
Embedded Subfile
The complete file MIE is wrapping, kept with its own original filename.
Place
The city, state and country recorded inside the file by whoever produced or catalogued it.
GPS Coordinates
Where the file was recorded, to within a few metres, when the format carries a fix.
Comment
Free text, stored once per language, so a single file may carry the same note in many locales.
Keywords
Keywords assigned to the file, which usually describe the subject or the job it belongs to.
Compressed Sections
How many parts of the file were zlib compressed and had to be decompressed to be read at all.

This is a selection. The full field manual documents the fields read from each format.

Questions about MIE metadata

What is a MIE file?

MIE stands for Meta Information Encapsulation. It is a container format designed to hold metadata of every other kind alongside the file it describes, so a single .mie can carry an image or a document plus its EXIF, XMP, IPTC, GPS and free-text notes in one place.

What metadata does a MIE file contain?

Typically the camera make, model, serial number and owner name, capture and modification timestamps, GPS and a named place, keywords, a title and copyright, free-text comments in multiple languages, a thumbnail, and the complete embedded file with its original filename.

Why do some tools report a MIE file as empty?

Because any element or whole group inside a MIE file may be zlib compressed, and a reader that skips compressed sections sees nothing. A file whose camera serial and owner name are one decompression away can be reported as carrying no metadata at all.

Can File X-Ray remove metadata from a MIE file?

No. MIE is read but not modified. Removing elements from it is separate work from reading them, and the tool does not claim a capability it does not have.

File X-Ray reads MIE files entirely in your browser - the file never leaves your device. This format is inspected, not modified. Scan a file now.
