WIM (Microsoft Windows Imaging Format) is a file-based disk image format for Windows. It is often used in Windows installers.

## Installation

On Linux, install wimlib to work on these files.

## View information

To view information about the WIM file (including but not limited to: name, index, etc…), use:

    $ wiminfo image_file

## Mount

WIM as an image file can be mounted with the following command

### Read-only mount

    # wimmount image_file index directory

### Mount as read/write

    # wimmountrw image_file index directory

### Unmount

    # wimunmount directory --commit

to apply the changes in the read-write mount.

Note: No changes will be applied without the `--commit` parameter.

## Directory structure

To view the directory structure of a WIM image, use:

    # wimdir image_file index

## Extract the image

To extract the full image, do:

    # wimapply image_file index target_directory

If you only need a few files from the image, use wimextract(1).

## Compression

The Windows ISO is larger than 4GiB, so it cannot be copied to a boot disk formatted with the FAT32 file system, you will need to compress `install.wim` to do this:

    # wimlib-imagex optimize install.wim --solid
