Though Cortana might no longer be the center of attraction on Windows 10 PCs, this doesn’t mean that Microsoft is not working on new features for its voice assistant. The latest Windows 10 Insider Preview build 20270 on the Dev channel allows Cortana to find and open files on your PC. You can simply ask it to open a recent file, file by a certain author, or a particular type of document (for eg. PDFs or Word docs).
This feature could be a boon for Enterprise users. Microsoft says that once you log in to your Windows 10 PC using corporate credentials, you can even search for and open the files saved on OneDrive and SharePoint. Cortana’s file search feature is just available to English-speaking users in the US.
