It's probably mostly block I/O cache. When data is read off disc it is
kept in RAM because reading from disc is very slow. Over time, more and
more will accrue in the RAM, ready for reuse if those files' data are
needed again. Given enough time, most of your RAM will be used for this.
This is not a performance problem - it is an advantage, because it
maximises your chance of having the data _already_ in RAM when it is
next desired.
It is also not a problem for having to "make RAM available" when it is
needed for something else. Data read from a file and stored in a memory
buffer is "clean" data - it is that same as what is on disc, and so does
not need to be put back there. Such a buffer may be _instantly_
discarded
and used for another purpose.
So most of this "used RAM" is "clean", so it is as though it were all
unused, should more memory be needed.

The more I know about the WIN32 API the more I dislike it. It is complex
and
for the most part poorly designed, inconsistent, and poorly documented.

You don't want to do it. Applications in need of memory will free some
of the cached memory for their own use.
