An incredible variety of disk cleaning software utilities are out there freely available for download and testing. Searching the internet reveals
utilities that specialize in helping you clean harddrive and many of these
also have other functionality too. However there are more things that these utilities
are able to do, for example some can clean up orphaned data, check the drive for
porn and remove it, find unlicensed software installed on the computer, and analyze your computer's
used and free space.
Although doing a computer cleanup generally has a positive outcome, we must also
consider the potential problems before going ahead. We must consider the likelihood
that files could accidentally be deleted, by the software we use or by our own hand.
Removing redundant or excess files takes time, more so if it is done by hand
but even using software for the task will take time as well. For most people these
risks are minimal and the clear improvements gained are good compensation for any
of these negatives.
