What is a PKG file?

A PKG file is a text file required to build an .SIS installer file, which is used to install applications on devices running the Symbian operating system (OS). It contains installation information in plain text that defines how to build the SIS installer file. PKG files typically include information about the languages supported by the application, vendor name, software dependencies, application files to copy, and details for digitally signing the file to verify its contents.

More Information

You will most likely only encounter Symbian PKG files if you are developing an application for the Symbian OS. The PKG file must be defined by Symbian developers in order to build a single distributable SIS installer file. When the application is ready to be built, developers typically use the "makesis" command, which is part of the CreateSIS utility. Developers may also use the Sisar or Easy SIS Creator applications, which provide a GUI for building SIS files.

Since PKG files are saved in plain text, they can be opened and modified with a text editor, such as Microsoft Notepad or Apple TextEdit, which are bundled with Windows and macOS. If you cannot open the PKG file with a text editor, you most likely have a different type of PKG file. This is due to various file types using the .pkg file extension, which includes the macOS Installer Package and PlayStation Store Download Package formats.

While SIS files are used to install applications, you can unpack the files if you want to view their contents. You can use the free UnSIS tool to unpack SIS files.

NOTE: In 2010, the Symbian Foundation ended and the Symbian OS was discontinued. Nokia eventually stopped accepting software from developers in 2014.
