Convert SISX to SIS

Understanding SISX and SIS file formats

The SISX file format is a package format used by Symbian OS to install applications, themes, and other software components on mobile devices. It is an extension of the older SIS format, which was also used for the same purpose. The primary difference between the two is that SISX files are used for Symbian OS 9.x and later, while SIS files are used for earlier versions of the Symbian OS.

Why convert SISX to SIS?

Converting a SISX file to a SIS file might be necessary if you need to install an application on an older Symbian device that does not support the SISX format. This conversion allows users to maintain compatibility with legacy devices.

How to convert SISX to SIS

Converting SISX to SIS is not a straightforward process due to the differences in the operating systems they support. However, certain tools and methods can help achieve this conversion.

Best software for SISX to SIS conversion

One of the most reliable tools for handling Symbian file formats is UnMakeSIS. This software can extract the contents of a SISX file, allowing you to repackage it into a SIS file manually. Here’s a basic guide on how to use it:

• Download and install UnMakeSIS on your computer.
• Open the software and use the File → Open menu to select your SISX file.
• Extract the contents of the SISX file.
• Manually repackage the extracted files into a SIS format using a SIS creation tool.

Note that this process may require technical expertise and might not work for all applications due to compatibility issues.
