What is a .wmz file?
A .wmz file is a WMF image. Its registered MIME type is application/x-msmetafile, which places it in the application or document family of formats.
WMF stands for Windows Metafile.
WMZ is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.
The same format is also saved with the extensions .emf, .emz, .wmf.
