File extension sis is associated with Symbian OS Installation Source.
Installer archive for devices that use the Symbian OS. Examples include Palm PDAs and Nokia, Ericsson, and Motorola phones; created using Symbian's CreateSIS program or the makesis command line tool.
Data in the .sis file is split up into two separate parts. The first part is the meta-data, describing the files that need to be installed. The second patrt of the SIS file contains all the actual file data.
SIS file format supports signatures and certificates to enable a package to signed. These signatures are verified during installation, and can also be re-verified after the package is installed on the device.
It also supports the compression of each of the files in the SIS file individually. This reduces the extra space needed to carry out installation.
