An EMZ file contains an Enhanced Metafile (.EMF file) that has been compressed with the .GZIP compression algorithm. It is compressed to reduce storage space and be more easily transferred between applications. EMZ files are typically used by Microsoft programs such as Visio and the Office suite, which includes Word and PowerPoint.

You can also open EMZ files by decompressing them with a GZIP decompression utility such as GNU zip (gzip.exe) or WinGZip. After decompressing the EMZ file, you can extract the EMF file contained in the EMZ file and open it with a program that supports the EMF format.
