I received a folder with a bunch of PDF files and one DJVU file. The PDF's open in PDF Complete but the DJVU does not. How do I open this type of file?

I would suggest SumatraPDF.
It opens PDF, XPS, DjVu, CHM, CBZ, CBR and is small and really fast.
You should visit a website suggesting software for various file types like this one: File Extension DJVU
Here are some examples of Windows software from the site:
