This feature is only available in iOS.
All files supported by your iOS devices will preview in the Docsvault app automatically. The Docsvault app also allows you to open files using other apps that support the file type.
Export a file to another app
•Click on the file you'd like to export to another app.
•The file will open in a file viewer inside Docsvault. Tap the share icon in top right corner.
•Tap the Open With/Open In... icon from the pop-up menu. A list of apps that can open the file will appear. Select the app you'd like to open the file in. For instance, clicking the mail button on the menu bar will send the file as an email attachment.
•You can even copy and print the file.
Note: Once you export the file to another app, any changes to the file will not be saved back to your Docsvault unless the file is uploaded back to Docsvault from the other application using the Open In menu in that application.
