File Extension WIM

.WIM File

File extension: WIM
File type: Imaging Format Archive


Notes about the WIM file extension:



To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The WIM file type is primarily associated with 'Windows' by Microsoft Corporation. Windows Imaging Format is a file-based rather than sector-based image format. This means that the disk image can use Single-Instance Storage (SIS) technology. SIS allows duplicate files to be stored only once. In addition, .WIM files are highly compressed so the image is about one-third of the original. You can use .WIM files without deleting the original partition/directory beforehand. It appears that Microsoft will be using .WIM files for some future deployments. 7-Zip claims to be able to unarchive a WIM file. The Microsoft Solution Accelerator for Business Desktop Deployment creates .WIM files for distribution.
