The following code can be used to query and delete files in the internet cache (including cookies). A demonstration routine can be found at the bottom of this post. Note, the enumerated type eCacheType is not supported in Excel 97, but can be changed to a list of Public Constants eg. Public Const eNormal = &H1&.
