You can probably use either WinZip or WinRar. The point is, you want the files to be uncompressed. That is, you want to have access to those files without having to use either WinZip or WinRar when you reboot in Safe Mode.
Once you have uncompressed files, just put them into the BFU folder you created. I'm not sure what you mean by 'viable file for browsing'...I suspect that this may mean that the files are not in .zip or .rar form.
Hope this gets you a little closer to a solution
