|Type of format||Disk image|
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, .CUE/.BIN used for CD and DVD images), WIM is file-based, which means that the smallest unit of information is a file. The primary advantages of it being file-based include hardware independence and single-instance storage of a file referenced multiple times in the filesystem tree.
