!Cache is a duplication of !Scrap and can be used for similar purposes, but provides alternative system variables and temporarily storage location for any application data which is perhaps required to be separate from !Scrap but not quite as permanent as Boot:Choices.

Simply install into !Boot.Resources in the same way as !Scrap. Dragging !Boot from the cache.zip archive will automatically install into the correct location on any machine with the universal !Boot sequence installed.
