How to open SIS files
Did your computer fail to open a SIS file? We explain what SIS files are and recommend software that we know can open or convert your files.
What is a SIS file?
We know of 2 different uses of the SIS file type, one of them being Symbian Installation Source. Read the details below.
The SIS file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a SIS opener may not be able to open all kinds of SIS files. In this case, look through both formats to make sure you find the best suited SIS viewer.
Symbian Installation Source
SIS is an acronym for Symbian Installation Source. Symbian OS developed the SIS file format for use on mobile devices such as PDA's and Cellphones.
Contrary to popular belief, files with the .sis extension are installation files and not application files. The real application file is the .APP file that the SIS file adds to the device that the application is being installed on.
The SIS files are created with the Symbian's "makesis" command-line tool included with the CreateSIS development program. Program developers will often use the CreateSIS program when creating applications for the Symbian operating system.
EPOC Installation package
Through our analysis of SIS files, we know that one use of the format is EPOC Installation package. We have not yet described in detail what these files contain and what they are used for, but our team is working tiredlessly through thousands of file formats. We'd love hearing from you if you have information about the format.
