It should, in the main, parse the aforementioned records properly although there's a small chance that this may not be the case for fields that contain large amounts of data. The script does not use the Extensible Storage Engine (ESE) API provided by Windows. The date stored in SPS property ID #24 (which is believed to be the actual last-visit date - the AccessedTime column appears to be when the record was last accessed) is presented in an unadjusted format tests indicate that it is stored as local-time. Run-time feedback is provided via the console window.ĭates originating from Extensible Storage Engine record-fields are presented as GMT. The script provides output in the form of bookmarks and a tab-delimited spreadsheet. Otherwise it will parse only WebCacheV01.dat files. If the user take takes the option to process tagged or selected files, the script will attempt to parse each file's structure regardless of its name. These records will also contain the aforementioned SPS value, but care should be taken with regards to the interpretation of that value see the script's internal help documentation for more details. The script has since been expanded to parse the records from all WebCacheV01.dat history tables including those maintained by the Edge browser. This value is thought to be stored in, or closely allied to, a serialized property storage (SPS) value with an ID of 6 located in the ResponseHeaders stream of records contained within the Internet Explorer medium-integrity history-table, which is identified by a partition ID value of 'M' in the WebCacheV01.dat Containers table. The script was originally created to decode the visit-count value displayed by Internet Explorer. This script parses history tables from WebCacheV01.dat Extensible Storage Engine database-files.
