How to Open an SIS File

SIS, which stands for Symbian Installation Source, is an archive file for the Symbian Operating System, which exists on many mobile devices. In other words, it's a zipped file for cell phones that contains a number of other compressed files. If you happen to have an SIS file on your computer, opening it and unpacking the files within is possible.

Instructions

1. Download the free program UnMakeSIS. (See Resources below.)

2. Open the downloaded folder and select Extract All Files. An extracted version of the folder will appear in the same location.

3. Open the extracted folder and double-click on UnMakeSIS.exe.

4. Press Open... at the bottom of the UnMakeSIS window and select the SIS file on your computer. All the files that the SIS contains will be listed in the Files box.

5. Extract the files from the SIS file by clicking Extract Files, next to Open.
