- Description
- MSLZ is an archive file format developed by Microsoft. It is a compressed version of the LZX compression algorithm which is used to reduce the size of files and folders. The files can be opened with the MSLZ Viewer, a free utility that is included with Microsoft Office.
- WinZip, starting with version 12.1, uses the extension .zipx for ZIP files that use compression methods newer than DEFLATE; specifically, methods BZip, LZMA, PPMd, Jpeg and Wavpack. The last 2 are applied to appropriate file types when "Best method" compression is selected.
