What are the files in the cache directory for?
The files in these directories are images and text that you have recently viewed. These files help speed up the display of images and text since retrieving data from your disk is faster than retrieving the data over the network. We suggest that you leave the files alone and Netscape will keep the file from growing beyond the files will be four megabytes unless you change the default. To view, delete or modify the size of the cache files • Select Options • Preferences • Network/Images/Security.
