Probably most of you who had been dealing with software had never heard or seen the file extension EMZ in your everyday life. Well I myself had never heard of it before until today. So as not to become naïve, I had done some research.It was just actually a Windows compressed file. These file extension EMZ are zipped or compressed image files of EMF format. Microsoft had developed such format to be used as image files in Microsoft Office Applications such as Microsoft Word and Microsoft Visio. The application tool used to compressed and decompressed EMZ files is called GZIP.
There are many ways to open an EMZ file extension such as using GZIP as I have mentioned above. Others had done it in unconventional ways like renaming its extension to .GZ and open it with WinRar. Another is the popular copy the file and paste it on a blank MS Word document. I tell you these stuff works.
