Want to reduce Cab file for QT application.

Hello,

My QT development details are as follows:
Visual Studio 2005
Qt version >>qt-sdk-win-opensource-2009.05
vs-addin
qt-vs-addin-1.1.2

I have made QT application for Windows Mobile. I have successfully made cab file for that application too. My main application filesize is just 350KB but due to dependency files whole application filesize has increased to 15MB. I have included following files.

>1.. QtGuid4.dll >> 11.5 MB

>2..QtCored4.dll >>3.21 MB

>3.. msvcr80d.dll >> 97.7 kb

>Total size of cab >> 15.1 MB

I want to reduce my cab file size till 3MB.
Please suggest me so that I can achieve this result.

Should I have to go for QT support?
Is prerequisite files need every time we make a .cab file?

waiting for your response.

Regards,
Ashfaque.
