yes they support doc but the basic features , if you use anothor font then its a mess all the documnt get just unrecognised well even if are showing th font is. actually i am using some presentation/ cun data work in word but when i open it in this libra office i found all is wrong and now i have to ue ms office again to work further in this project.
well , in this new version it satisfied me but still i havnot got the whole features like ms office do.
it will depend on what fonts installed on the Libre Office/MS Office
but even with both platforms using same fonts, there are still some features that aren't fully compatible... but it's less than before...
