This article describes how to search for hidden or system files in Windows XP.By default, the Search companion does not search for hidden or system files. Because of this, you may be unable to find files, even though they exist on the drive.
To search for hidden or system files in Windows XP:
Click Start, click Search, click All files and folders, and then click More advanced options.
Click to select the Search system folders and Search hidden files and folders check boxes.(Please look the screenshots below of this article,numbering 1,2,3,4 sequence wise.)
You do not need to configure your computer to show hidden files in the Folder Options dialog box in Windows Explorer to find files with either the hidden or system attributes, but you need to configure your computer not to hide protected operating system files to find files with both the hidden and system attributes. Search Companion shares the Hide protected operating system files option (which hides files with both the system and hidden attributes) with the Folder Options dialog box Windows Explorer.
This trick applies to Microsoft Windows XP Home Edition Microsoft Windows XP Professional Edition.
