Support for FFU Files

Are there any plans for DISMTools to support managing and servicing FFU images in the future?

FFU (Full Flash Utility) images are definitely in the same family as WIM—both are used by Windows for image-based deployments. While DISMTools currently focuses on WIM, FFU support would be a natural extension because DISM itself can handle both formats (using /Get-WimInfo vs /Get-FfuInfo under the hood). The main differences are: FFU is sector-by-sector and includes disk layout metadata, while WIM is file-based and more flexible for layering. If you need FFU management today, you can fall back to the DISM CLI directly (e.g., dism /Get-FfuInfo, /Mount-Ffu). Adding native FFU support to DISMTools would just wrap those same APIs. So keep an eye on the repo—this is a reasonable feature request that could happen if there's enough demand.

FFU support will not be implemented in 0.7.3 since it's too late for that down the pipeline. However, I plan on adding it in 0.8.
