The features that distinguish Sumatra PDF from other PDF readers are its built-in editing tools and the large size of the text pages. Once the software starts working, it automatically identifies all the places where you have modified documents in the PDF file and displays them for you, so that you can go back to them to change them accordingly. It also includes an extensive library of special characters, which enables you to include formulas and other symbols in your documents. Sumatra PDF Portable also features a password protection facility, which protects confidential material. If you have a printer, you can print PDF files out using the application on a PC, as well as providing you with an option of printing the files directly from your digital camera.
