The file extension PKG identifies PlayStation Store Downloaded Packages, ie downloadable software from the Playstation Store. This includes movies, games and demos for the Playstation 3 and PSP. In addition, game updates in this format are offered. PKG files are encrypted files, which can be installed exclusively on the Playstation.

How to open a PKG file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the PKG 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 PKG 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 PKG files. At this point we are looking for disk space where the application was installed in and we can link it with a PKG file. Since then, our operating system will use the selected program to support all PKG files.

Other issues

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

- verify that the PKG 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 PKG 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.
