The document sharing feature of WhatsApp allows users to only share PDF files for now. This means that there is no support for .doc, .xls and other commonly used file formats; there is no official word on when the company will start supporting these.
In order to share files, you need to tap the attachment icon on the top right of the screen in a chat window and select the ‘Document’ option. This opens a list of PDF files stored in the system, but the navigation does not let you open specific folders.
This update, however, has not been released to all Android users via Google Play. Those who are yet to receive the document sharing feature can click this linkand download the install file directly from the official website.
The new feature for Android comes just a day after WhatsApp added new features to its iPhone app, including cloud storage integration for sending photos and videos.
