Varying free storage?


In 2013, our Vista SP2 Business PC (that OS was pre-installed, and actually great. In our experience, Vista worked as great as Windows 7) with 1 TB HDD had 610 GB free. Suddenly, after a few days, 627 GB were free, then 598 GB, without doing much. Then back to 618 GB free.

Not that I mind it, but what did possibly cause the storage to get 17 GB free, then 29 GB filled, then 20 GB less?

Many background resources will contribute to such manor variations ( on a 1TB drive 20GB is approx 2% of the drive) Such variable usage includes the pagefile and swapfile (temporary usage of hard drive to temporarily accommodate constantly varying RAM images) and virtual memory.
