In what was CCleaner developed?

Hi,

I would like to ask in what was CCleaner developed?

I am interested in the programming suit, because CCleaner is so small and lightning fast, not like .NET.

Thanks

c++ so i'm told. Not sure if it was made in visual. This is not really a ccleaner suggestion though.

Unfortunately, the developers are too busy to answer.

I don't think that it was made in visual studio, because from about 2002 all MS programming tools are based on .NET.

Version 2.0

CCleaner 2.0 is completely rebuilt in C++[3] and portable and compatible with all 64-bit versions of Windows XP and Vista. The scanning process was also rewritten in C++, which enabled faster analyzing and cleaning. Its design also makes it capable of being installed onto a USB flash drive, which ensures portability.
