Information, tips and instructions

Open PKG File

A PKG file, diminutive of "Package", is simply a package of installation files. These files are used by the Mac Operating System and are executed when a user wants to install a program or a software on the computer.

The PKG file is similar to the MSI installation files used by computers running the Microsoft Windows operating system. If you have downloaded a program for your Apple Mac, the program installation files may be contained in a PKG file.

You can open PKG file and install it by either double-clicking on it or Ctrl-clicking on the PKG file and selecting "Open with...->".


You can view the contents of the PKG file on your Mac without installing it by right clicking on the file and selecting "Show package content" in the context menu. To install the program from a PKG file, double-click the file.

Symbian OS

The Symbian operating system on some mobile devices uses PKG files to package the application execution SIS files in this system. This packaging information is stored in text form inside the PKG file and includes instructions, information and command lines.

You can open a Symbian PKG file and view the content on a computer with Windows OS using various utilities, such as: UnSIS, Easy SIS CreaTor and CreateSIS. Although you can see the contents of the file on your computer, you can only install the application that contains the file on a smartphone with the Symbian operating system.

3D Modeling

CoCreate Modeling software uses the PKG file extension to compress and package the files necessary for downloading a 3-D model.

The PKG format reduces the size of the files and makes them easier to download in a single session. You can view and open PKG files with CoCreate Modeling or the previous software versions known as SolidDesigner or OneSpace Designer.
