This is the download cache for managed user controls aka .NET ActiveX
controls. If you arent running those types of applications, the dir should
be empty. When you build a managed user control (a windows control hosted in
a web form) and request that page in a browser, IE downloads the assembly to
that directory and sets up a sandbox against the bits in there. CAS policy
is applied to the bits and execution begins subject to CAS policy of-course.
Since it's part of the GAC, you can manipulate it, clear it, purge it using
gacutil /cdl which Clears the DownLoad cache.
