If you want to stop working on a document, you can close it at any time. If the document has been modified since it was last saved, the program automatically asks you if you want to save the document first.
To close a file, you have the following options:
Ribbon commands
Choose the command File | Close to close the current document.
Choose the command File | Close all to close all currently open documents at once.
Tip: You will also find both commands on the ribbon tab View | group Documents.
Document tabs
Above the document, you will find a bar with document tabs for all currently open documents. If you click on one of these tabs with the middle mouse button, the corresponding document is closed.
Alternatively, left-click on the x icon displayed on the far right of each tab to close it.
Via the keyboard
You can also use the shortcut key Ctrl+F4 to close the current document and Ctrl+Shift+Alt+C to close all open documents.
Exiting the application
To exit FlexiPDF, choose the command File | Exit (the button is located at the bottom right of the open File menu) or use the keyboard shortcut Ctrl+Q.
Alternatively: Simply click on the x icon on the far right of the title bar at the top.
