What does the Paging file have to do with VCACHE ? Where does VCACHE's data
live?

One way is to disable virtual memory and then reboot.


Why would that do it and what is the potential for adverse effects?


I should have added that right after the first reboot, go back and
'enable' it and reboot again.
Unless you have a lot of programs running at first boot, there should
be no adverse effect.

Another way would be to put your virtual memory on another

partition.

Why would that work ?


After the first reboot, the old swp file would be emptied because the
new swap file would be on another partition.
Not a good way to do it, but I was giving another way to 'empty' the
swap file.
Actually, I never should have mentioned it.

Another way would be to delete its contents while in real-mode

DOS.

Looking back, I should have just suggested the below.

Why do you want to do it?
It just rebuilds by itself.
There are free 'memory-saver-boost' programs that will do it, but

most
consider them to be snake-oil type programs.
What is the problem you are having.

I believe it 'lives' in win386.swp .
If you put that in Find, you will find yours. (Hidden files checked to

I believe that VCACHE data lives in the locked pages of RAM.

Why would VCACHE store data in the paging file and then have to read the
data back to store it in the real file ?

This is from the Wn 98 Resource Kit. Search for Locked and then click
Installable File System from the list:

The 32-bit VFAT works with a 32-bit, protected-mode cache driver (VCACHE).
This driver replaces the 16-bit, real-mode SMARTDrive disk cache software
provided with MS-DOS and Windows 3.1. The VCACHE driver features better
caching algorithms than SMARTDrive, to cache information read from or
written to a disk drive. The VCACHE driver also manages the cache pool for
the Universal Disk Format File System (UDF) and the 32-bit network
redirectors provided with Windows 98.

Another big improvement in VCACHE over SMARTDrive is that the memory pool
used for the cache is dynamic and is based on the amount of available free
system memory. Users no longer need to allocate a block of memory as a disk
cache. The system automatically allocates or deallocates memory used for the
cache, based on system use.

For example, as you perform a large number of activities on the network,
Windows 98 increases the size of the cache. As network activity decreases
and more applications are started, Windows 98 decreases the cache size.

Another improvement made to VCACHE in Windows 98 is the ability of VCACHE
and the memory manager to execute applications that are present in the
cache, directly out of the cache memory. This is referred to as cache
mapping and improves the efficiency of memory utilization.

Remember you can monitor locked pages via System Monitor.

Why did post say that VCACHE data lives in Paging file?
