- Description
- An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
- A WMZ file is a Windows Metafile (.WMF) compressed with GZIP. Microsoft Office and Visio save vector graphics this way to reduce their size. Windows Media Player skins also use the .wmz extension, but those are ZIP archives and are a different format.
