Cache folder is the one which has all the files downloaded and viewed while browsing the internet .Many browsers like opera and Seamonkey make use of the cache to make loading of pages faster by loading the web page from the cache rather than the internet . This helps in saving a lot of bandwidth and also increases the speed of browsing and hence cache is very important.
Many people delete cache because of the privacy concerns and hence all info in the cache is lost and hence browsing gets slower as if you are opening the web page for the first time.
Anyway the default cache folder for seamonkey is inside the user document folder . You can change it like this:
Got o seamonkey and open edit > preferences and expand the node advanced and select cache.
In the select cache location label you can browse for the folder in which you want the cache instead.
