You have forgotten to tell us which drive and if you have more than the one
drive. Supposing you have two as most people have
"Most people"? On the contrary, it's extremely rare than anyone has
more than one physical drive.
Two partitions on a single physical drive is much more common, but
even there, I doubt very much if it's anywhere near "most people."
and you are properply
organised having OS on a 10 GB partition
"Properly"? There is no "properly." How to arrange your partitions is
mostly a matter of individual preference.
then you may some day have lack of
space and you can proceed like this:
For the purpose of recovering space on your C: Drive, you should change the
Location of the Paging File. I can take as much as 2 GB on the partition where
you should
Again, there is no "should." And for most people, it's much better to
keep installed programs on the same partition as the operating system.
only have the Operating System.
Putting the Page File on a second partition is not a good idea, and
can hurt your performance. What it does is move the page file to a
location on the hard drive distant from the other frequently-used data
on the drive. The result is that every time Windows needs to use the
page file, the time to get to it and back from it is increased.
Putting the page file on a second *physical* drive is a good idea,
since it decreases head movement, but not to a second partition on a
single drive. A good rule of thumb is that the page file should be on
the most-used partition of the least-used physical drive. For almost
everyone with a single drive, that's C:.
If you have enough RAM, the penalty for moving the page file to a
second partition may be slight, since you won't use the page file
much, but it won't help you.
