This article mainly introduces what the wim file format is, which is very detailed and has certain reference value. Friends who are interested must finish reading it!

Wim is the Windows file-based image format, its English full name is Microsoft Windows Imaging Format;wim image format is not quite common sector-based image format, it is file-based; wim files store one or more copies of the operating system.

WIM is the abbreviation of Microsoft Windows Imaging Format (WIM). It is the file-based image format of Windows. The WIM image format is not the sector-based image format that is quite common today, it is file-based. Windows Vista installs quickly on new computers in this format. WIM files store copies of one or more operating systems, such as Windows Vista or Windows PE, called images. Using WIM files to maintain the operating system is easy because you can add and remove drivers, updates, and Windows components offline without starting the operating system. Maintaining the Windows PE image with WIM files is very similar to maintaining the Windows Vista image.

Compared to other formats, WIM has the following benefits by using a file-based image format:

WIM is a file-based image format

The WIM image format is hardware agnostic, which means that you only need one image to address many different hardware configurations.

The WIM image format also allows you to store multiple images in a single actual file. For example, Microsoft can include multiple SKU in a single WIM image file. You can store images with or without core applications in a single image file. Also, you can mark one of the images as bootable, allowing you to boot your computer from the disk image contained in the WIM file.

The WIM image format also enables compression and single instance, which greatly reduces the size of the image file. A single instance is a technique that allows you to store multiple copies of files with the space of one copy of a file. For example, if images 1, 2, and 3 all contain file A, a single instance stores a single copy of file An and points images 1, 2, and 3 to that copy.

The WIM image format allows you to maintain the image offline. You can add or remove some operating system components, patches, and drivers without creating a new image. For example, for Microsoft Windows XP, it now takes several hours to update an image, while Windows Vista only takes a few minutes. For example, to add a patch to the Windows XP image, you must boot the primary image, add the patch, and then prepare the image again. For Windows Vista, you can maintain the image offline.

Unlike the sector-based image format that requires you to deploy a disk image to a partition whose capacity is greater than or equal to the capacity of the source disk, the WIM image format allows you to install a disk image on a partition of any size.

Windows Vista provides an API for the WIM image format called WIMGAPI, which developers can use to process WIM image files.

The WIM image format allows for non-destructive deployment. This means that you can keep the data on the volume to which you applied the image, because the application of that image does not erase the existing contents of the disk.
