Why did you zip the files and why did you prefer to use winrar instead of winzip?
A. To be able to reduce the volume of the files and to help you download the files faster, we zipped all the files. In some cases the compression rate was %85-90, especially with the files made with VBR mode. WinRar compresses with much higher compression rates than the WinZip. For that reason we prefered WinRar.
