Hey, did you know that the Libreoffice that came packed with this cinnamon will open MS word .docx files? I just went and grabbed a couple to try it from my windows partition files to try it.
I think it is cool that while in Linux you can go grab your windows files from out of the windows folders when you have it dual boot like this.
Yeah, Open/LibreOffice has had the ability to open and save Office 2007 format files (the ones ending in x) for many years. They default to the Open Document formats, but you can select Office 2007 format.
