How can I choose which PDFs to save to my Locker?

Always Save to Locker (View PDF) / Always save to PDFs to my locker (Settings)

By default, Kopernio automatically saves PDFs you access in your Kopernio Locker (you can remove these again any time you want). 

You can turn this off by unticking Always save to PDFs to my locker at Settings > General > Locker Usage. 

The same option to untick Always save to my locker will also appear in the PDF viewer when you remove the PDF from the Locker. 

Save to Locker / Remove from Locker?

In the PDF Viewer, the Save to Locker button can change behaviours based on the save state of the PDF. 

The Save to Locker button is white when the PDF does not exist in the locker. Clicking on it will start the saving process and it will turn green when it is saved. 

If the Save to Locker button is green it means the PDF is already in your Locker. Hover over the button reveals the Remove from Locker. Clicking on it removes the PDF from Locker

Changes in your Locker will be reflected in a synced Dropbox.
