Open/Extract WIM File with Freeware on Windows/Mac/Linux


WIM FileWIM (Windows Imaging Format) is WIM is a file-based disk image format that was introduced in Windows Vista. WIM files are compressed packages that contain a number of related files. The format of a WIM file is optimized for maximum compression with LZX, for fast compression with XPRESS, or uncompressed.

A WIM file structure contains up to six types of resources: header, file resource, metadata resource, lookup table, XML data, and integrity table. The following illustration shows the general layout of a WIM file that contains two images.

Like other disk image formats, a WIM file contains a set of files and associated filesystem metadata. However, unlike sector-based formats (such as ISO or VHD), WIM is file-based: The fundamental unit of information in a WIM is a file.

WIM files can contain multiple disk images, which are referenced either by their numerical index or by their unique name. Due to the use of single-instance storage, the more each successive disk image has in common with previous images added to the WIM file, the less new data will be added. A WIM can also be split (spanned) into multiple parts, which have the .swm extension.

WIM images can be made bootable. Windows boot loader supports booting Windows from within a WIM file. Windows Setup DVD in Windows Vista and later use such WIM files. In this case, BOOT.WIM contains a bootable version of Windows PE from which the installation is performed. Other setup files are held in the INSTALL.WIM.
