When you delete a file from your PC, is it truly erased? Without getting into the fine details of how files are stored on and then deleted from your hard drive, the one-word answer is “NO”.
A deleted file is not erased from your hard drive. In fact, it is easy to recover immediately after the deletion, but gets harder over time.
What is the deleted file contained personal or financial information? A hacker could recover the data and use it in ways that you might not like. So what are you to do?
A simple way to make sure that the information in a file is actually deleted from a drive and not able to be recovered is to use a special deletion program like File Shredder (www.fileshredder.org). File Shredder writes a series of random 1’s and 0’s on top of the drive area where your file was stored. You can choose different levels of “shredding” (from a single pass, to a Department of Defense (7-pass) standard to the ultimate “Guttman” (35-pass) standard.)
Once you have deleted a file using File Shredder, it is actually gone from your drive and safe from any prying eyes.
Thanks for the points you have discussed here. Another thing I would like to mention is that computer system memory requirements generally increase along with other advances in the technologies. For instance, any time new generations of cpus are introduced to the market, there’s usually an equivalent increase in the scale preferences of all computer memory in addition to hard drive space. This is because the software operated simply by these cpus will inevitably rise in power to benefit from the new technological know-how.
