Marty List brings us WFPQuery, which allows you to query the list of files protected by Windows 2000/XP. You can export the entire list of protected files, or specify the files to query based on patterns/wildcards.

The readme contains:

Windows File Protection Query \[Version 1.00\]

Queries the Windows protected file list.

The syntax of this command is:

WFPQuery.exe /list|filename \[filename2 filename3 ...\]

 /list|/l       Displays the complete list of system protected files,
                All other parameters are ignored.

 If /l is not specified, one or more files can be queried individually.
 Separate multiple files with spaces; enclose paths containing spaces in quotes.

 An argument of /? or -? displays this syntax and returns 1.
 A successful completion will return 0.
