Restore all Files from an FSA Archive (include duplicate filenames)

Hi, 

we´ve got a problem in our EV environment. So we have to restore all of our archived Files (FSA) an rearchive them in a new sturcture.

I know that this is possible with the fsautility.exe, but the problem is that we have files with duplicate filenames in the archive.

If I restore all the files from an archive with the fsautility, it "de-duplicates" the files and restores only the file with the newest change date. 

This caused problems with the law. We have to proove all the changes of one file.

How can I get all files, including the duplicated?
Are there any hidden options in the fsautility?

Thanks.
