Caching, the cache directory, and ".moz" files

A "cache" (pronounced like "cash") temporarily stores on your computer
the information from web pages you've visited.  If you later revisit a
page that is stored in the cache, Netscape Navigator can retrieve the
page from its cache more quickly than retrieving the page again from
its location out on the network.
The files in Netscape Navigator's "cache" directory are given cryptic
names (such as "cache2093120-2"), and on Windows they have a ".moz"
extension; there may be hundreds of these files in the directory.
Don't bother trying to view or delete any of the files in the "cache"
directory yourself; Netscape Navigator will use them when it needs to.
If you want to reduce the amount of disk space the cache files are
taking up on your disk, go into the Netscape Preferences and reduce
the "Cache Size" setting.  You can also press the "Clear Disk Cache
Now" button to completely empty out your cache (but it will gradually
fill back up to the "Cache Size" setting as you browse the web).  The
lower your "Cache Size" setting is, the less space the cache will take
up on your hard disk, and the more often Netscape Navigator will have
to reload files from the network (slowing it down) because it doesn't
have the files in its cache any longer.  (If the cache is full, pages
that haven't been visited for a long time will be removed to make room).
