Windows puts an area of the size of about 80% of the RAM on the local
disk. This is the "file system cache". Windows doesn't show you this
file system cache, but you can imagine it as a large file normally on
your Drive C.

Not really, where did you get that info, as this is not "file system cache"
Please back this up with a technical article


When you do large file copies to your disk, you can
monitor the increasing of the cache in the task manager. In this moment
the copied files do not stay in the directory where you meant to copy
them. They are in the file system cache.

the copy comands WILL LEAVE a copy in the original directory !
Please ensure you do not mix the term copy with the term move.
And NO, this is not a good explanation of file system cache
Please backup your claims with some technical article



This can last a long time
until the file system cache is emptied an written to the real location.
Microsoft knows that there are problems with the file system cache when
you have machines with much RAM.

Please backup your claim with a technical article.



Maybe when you backup a system and the
file system cache is not empty there can be a loss of data. In large
domain environments, this can cause problems, if the file system cache
is to big. There may be replication problems. To fix the problem some
companies go the way and reduce the memory of domain controllers to
256MB RAM. Because then the file system cache is 80% of 256MB, and the
problems are gone. There is no way to reduce the file system cache
manually (The only way is reducing RAM). You can find registry hacks,
but they dont work.

Again, sorry to be repetative... please, PLEASE, back up your stories with
some technical facts.

There is never a shortage of free memory!

System cache is in memory. It is not on the drive.

And as I said, this is a good thing. When your system needs to cache
to the
hard drive because the RAM is needed for other tasks, it will do so.
As it
stands now, your system is running optimally. No need to change
anything.
