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 & .OPTION Explicit '------------------------ Types, Consts and StructuresPrivate const error_cache_find_fail As Long = 0Private Const ERROR_CACHE_FIND_SUCCESS As Long = 1Private Const ERROR_FILE_NOT_FOUND As Long = 2Private Const ERROR_ACCESS_DENIED As Long = 5Private Const ERROR_INSUFFICIENT_BUFFER As Long = 122Private Const MAX_CACHE_ENTRY_INFO_SIZE As Long = 4096Private Const LMEM_FIXED As Long = & H0Private Const LMEM_ZEROINIT As Long = & H40Public Enum eCacheTypeeNormal = & H1 & eEdited = & H8 & eTrackOffline = & H10 & eTrackOnline = & H20 & eSticky = & H40 & eSparse = & H10000eCookie = & H100000eURLHistory = & H200000eURLFindDefaultFilter = 0 & End EnumPrivate Type FILETIMEdwLowDateTime As LongdwH ighDateTime As LongEnd TypePrivate Type INTERNET_CACHE_ENTRY_INFOdwStructSize As LonglpszSourceUrlName As LonglpszLocalFileName As LongCacheEntryType As Long 'Type of entry returneddwUseCount As LongdwHitRate As LongdwSizeLow As LongdwSizeHigh As LongLastModifiedTime As FILETIMEExpireTime As FILETIMELastAccessTime As FILETIMELastSyncTime As FILETIMElpHeaderInfo As LongdwHeaderInfoSize As LonglpszFileExtension As LongdwExemptDelta As LongEnd Type' ----- --------------------- Internet Cache ApiPrivate Declare Function FindfirstURLCAENTRY LIB "Wininet.dll" Alias "
