the PDF the most used document format on the Internet. It is used by many companies for manuals and datasheets, but also governments and other organizations use PDF very often.

A PDF can contain texts, pictures, graphics as well as vector drawings or 3D objects. The advantage of PDF lies in the fact that there are display programs on every platform and normally the complete layout (arrangement of pictures, fonts, etc.) is displayed the same everywhere. PDF documents can also be encrypted and work with Digital Rights Management (DRM), which is why you can find PDF more and more often in e-book stores.

How to open a PDF file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the PDF file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a PDF file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support PDF files. At this point we are looking for disk space where the application was installed in and we can link it with a PDF file. Since then, our operating system will use the selected program to support all PDF files.

Other issues

Despite the described problem with PDF there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the PDF file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the PDF file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
