What is the difference between a paging file like pagefile.sys and the
cache.

Under Win ME win386.swp was the cache, but this seems to have gone from XP?

A swap or paging file acts much like additional ram for your computer. Say
you have 5 open applications and when you open a sixth, you run out of
physical ram. The os will swap the ram being used by the inactive
applications out to disk and make the physical ram available to the active
application. It is a bit more complicated than that but that's the gist of
it.

Assuming you are talking about IE cache, it is a placed where pages that
you have visited in the past are stored so that the next time you go to
them, the text or the graphics or maybe even the whole page can be loaded
from your harddrive instead of the server which is of course faster. Again,
it is a bit more complicated than that.

As its extension implies, win386.swp is a swap file not a cache.

A paging file is a disk file that is used to compensate for the lack
of sufficient physical RAM to meet the total memory requirements of
the computer.

A cache, in the most general terms, is a small area of high speed
storage that is used to augment the performance of a lower speed
storage by storing the most recently and/or the most frequently used
items from the lower speed storage.

Thus a CPU chip has an on-board cache where program instructions are
stored so that they can be accessed faster than they can from RAM.

Windows uses a disk cache to store recently read data from the hard
drive in RAM because RAM is much faster to access than is the hard
drive.

Web browsers use a data cache on the hard drive to store recently
accessed information from web pages because the hard drive is usually
faster than getting the information again from the web site,
especially with a dial-up Internet connection.


In WindowsMe the Win386.swp was the Swap file, which is the equivalent
of the paging file in Windows XP. The only cache in WindowsMe that
existed as files was the web browser cache, which was in the Temporary
Internet Files folder, the same as it is in Windows XP.

Hope this clarifies the situation.

Good luck

no, win386.swp was the swap/pagefile. NOte the .swp stands for swap
