This should indicate that only 26% of your C: drive is occupied by system and application/data files, leaving the remainder available for subsequent use. In other words this is a good thing, there is space available on C: for installing more applications etc. On my laptop C: partition, the figures are Used space 6.59GB, Free space 5.12, so my usage is just over 50%.
This is not at all related to virtual memory. A 756MB paging file would be typical for 512M of RAM. Now having 2GB available, the paging file size can be less significant, as there is so much more memory available we would expect there to be much less need for use of the paging file. However if you load the system up heavily, a similar guideline would apply, that a pagefile of 1.5 times the physical memory is suggested.
One way of handling it is to allow Windows to manage the pagefile, setting the "System managed size" in the Virtual Memory properties. Windows is actually quite good at managing virtual memory. But if you want to specify sizes, setting the minimum and maximum size the same yields a fixed pagefile size, whereas setting a smaller minimum size with an adequate maximum, saves using up say 3GB of the drive with a permanent file that may rarely be used.
