Microsoft [[Windows]] uses a '''paging file''', called <tt>pagefile.sys</tt>, to store frames of memory that do not current fit into [[physical memory]]. Although Windows supports up to 16 paging files, in practice normally only one is used. This file, stored in <tt>%SystemDrive%\pagefile.sys</tt> is a hidden system file. Because the operating system keeps this file open during normal operation, it can never be read or accessed by a user. It is possible to read this file by parsing the raw file system (e.g. using [[The Sleuth Kit]]).

Plaso (plaso langar að safna öllu) is the Python based back-end engine used by tools such as log2timeline for automatic creation of a super timelines. The goal of log2timeline (and thus plaso) is to provide a single tool that can parse various log files and forensic artifacts from computers and related systems, such as network equipment to produce a single correlated timeline. This timeline can then be easily analysed by forensic investigators/analysts, speeding up investigations by correlating the vast amount of information found on an average computer system. Plaso is intended to be applied for creating super timelines but also supports creating [http://blog.kiddaland.net/2013/02/targeted-timelines-part-i.html targeted timelines].
  
Data is stored in the paging file when [[Windows]] determines that it needs more space in physical memory. Because storage locations in the paging file are not necessarily sequential, it is unlikely to find consecutive pages there. Although it is possible to find data in chunks smaller than or equal to 4KB, its the largest an examiner can hope for.

The Plaso project site also provides [[4n6time]], formerly "l2t_Review", which is a cross-platform forensic tool for timeline creation and review by [[David Nides]].
  
Sadly, the most productive method to date for analyzing paging files is searching for [[strings]]. It is possible to [[Carving|carve out files]], but as noted the examiner is unlikely to find anything larger than 4KB.
