File Extension PDF
Definition
The Portable Document Format (PDF) is the file format created by Adobe Systems in 1993 for document exchange. PDF is a fixed-layout format used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system. Each PDF file encapsulates a complete description of a 2-D document (and, with Acrobat 3-D, embedded 3-D documents) that includes the text, fonts, images, and 2-D vector graphics that compose the documents.
Windows Cannot Open PDF Files?
If Windows cannot open PDF files you may not have the appropriate program installed or have a registry related error. We strongly recommend you run a free registry scan.

Windows Registry is a critical component of your Windows operating system that governs
the operation of Windows. Without a clean and well-organized registry, your Windows system is vulnerable to corruption,
freezing, and crashing.

Computers perform best when they receive regular, professional maintenance. The installation and un-installation of software, hardware, and drivers often leave remnants behind in your registry, resulting in a tangle of unused applications, broken drivers, and incomplete and empty command signals. This mass of confusion slows down your computer and if not addressed promptly can lead to serious problems such as computer not recognizing file extensions, freezing, programs not responding, and system crashes.
