X-Ways Trace: Browser Log Files Deciphered

X-Ways Trace 3.0

Download
eval. version

A computer forensics tool that allows to track and examine web browsing activity and deletion of files through the Windows recycle bin that took place on a certain computer.

Deciphers Internet Explorer's ever-growing internal history/cache file index.dat. Displays complete URLs, date and time of the last visit, user names, file sizes, filename extensions, and more. Allows to sort by any criterion. Reads from one more more files you specify, or searches complete folders and subfolders, or even entire hard disks (or raw images of hard disks) in allocated space, free space, and slack space, for traces of someone having surfed the Internet. Occassionally, accesses to local files are logged, too. You may search for specific domain, file, and user names.

Also deciphers the browser history file "history.dat" produced by Mozilla/Firefox and the browser cache file "dcache4.url" created by the Opera browser.

Also deciphers the hidden Windows recycle bin file info2 located in every Recycled/Recycler folder. Displays the original path and filename, date and time of deletion, file size, and more, sometimes even if the recycle bin has been emptied.

All the details compiled by X-Ways Trace can be exported to MS Excel. The files/disks examined by X-Ways Trace will not be altered by the examination. X-Ways Trace is part of Evidor, but can be ordered separately. Other available languages: .  

From the Microsoft Knowledge Base Article 322916:

The Internet Explorer Index.dat File in the History Folder May Become Very Large.

The information in this article applies to: Microsoft Internet Explorer 5.5 for Windows NT 4.0, 5.01 for Windows NT 4.0, 5.0 for Windows NT 4.0, 5.5 for Windows 98, 5.01 for Windows 98, 5.0 for Windows 98, 5.5 for Windows 2000, 5.01 for Windows 2000, 5.0 for Windows 2000, version 6 for Windows 98/Windows NT 4.0/Windows 2000/Windows XP.

Symptoms: The Internet Explorer Index.dat file in the History folder may become very large over time.  

Cause: The Index.dat file is never resized or deleted. Clearing the Internet Explorer history by clicking the Clear History button on the General tab in the Internet Options dialog box does not change the size of the Index.dat file. Also, setting the Days to keep pages in history value to 0 (zero) on the General tab does not change the size of the Index.dat file. The pre-allocated space in the Index.dat file increases Internet Explorer performance.
