Right Joe.
Here I am dreaming again, while reading my E-Mail on MSWIN98.
Of course you got me. At some point a program will request
more memory than is physically present on your computer.
That is when an operating system like M$WIN9X will call up a
least-recently used (LRU) algorithm that determines what
portion of memory it can free up by writing the contents
to a disk-based swap file if necessary. Once the swap file is
updated, the physical memory addresses can be overwritten
with the data requested by the program. In MSWIN9X/ME this
is called SWP386. It will be placed on the c:\ drive by default
and sooner or later it can grow so large that you can not even
save a file to disk C:\. It is recommended that you put it on
your fastest hard drive unless that is C:\. It would be best to
make a small partition about 3 times as large as your system
ram and put the SWP386 file there, where it will not interfere
with what you have on program or data partitions. I have had
my SWP386 file grow to over 4GB and freeze up my computer
after using the internet for 5 or 6 hours, and I have 32MB of
system ram installed.
I will try not to mix WINDOWS stuff up with DOS in future.
