EMZ files are image files which are used by the Microsoft Office suite and Visio, an application created by Microsoft for drawing 2D objects. Files that contain the .EMZ extension are compressed using the Gzip compression algorithm. After they are decompressed, they can be opened as standard Enhanced Metafiles. EMF is a vector graphic format which is used by a variety of different image editing applications.
EMZ files contain information related to images which are used to create diagrams in office applications. They are vector graphics used in spreadsheets, office documents, slide presentations, and databases and can be tricky to read since they are limited to the Gzip algorithm.
How to Open EMZ Files
EMZ files can be opened and viewed across multiple operating systems, including Windows, Mac OS X, and Linux. Since EMZ files are compressed using a Gzip algorithm, you must use decompression software that unzips files in this type of compression format.
Depending upon the operating system you use, you can unzip EMZ files with a Gzip decompression utility for Windows such as GNU or WinGZip. If you have one of the recent versions of Microsoft Office or Visio installed, you can easily open and edit EMZ files with one of these programs.
For Mac OS X or Linux it is necessary to use XnView which allows you to view EMZ files and convert the file format to one of 400 different graphics formats. XnView works in conjunction with NConvert to view and convert EMZ files and is compatible with Mac OS X, Linux, Linux ppc, FreeBSD x86, OpenBSD x86, NetBSD x86, Solaris sparc, Solaris x86, Irix mips, HP-UX, and AIX.
NConvert works with Mac OS X, Linux x86, Linux ppc, FreeBSD x86, OpenBSD x86, NetBSD x86, Solaris sparc, Solaris x86, Irix mips, HP-UX, AIX, OS/2, Atari, and BeOS x86 for converting EMZ files.
Other programs that can be used to open and view EMZ file formats include Konvertor which is freeware designed for opening and viewing graphics and converting the file to a variety of different formats. Factory Image Converter is capable of converting EMZ files to PDF, ICO, TIFF, JPEG, and BMP file formats, and First File View which is a viewing and printing application that automatically detects the format and opens it without having to use the authoring application. These programs are available online as a free download from websites such as Softpedia and CNET.
