SkinCrafter skin file (.skf)
.skf file signature | application/octet-stream
SkinCrafter skin file is a proprietary theme file format created and maintained by SkinCrafter, a Windows user interface skinning toolkit. It is used to define the appearance of application controls, windows, and dialogs in programs that support SkinCrafter-based customization for desktop applications. The format is generally considered safe, though its usefulness depends on legacy software that still includes SkinCrafter support.
