How to Remove Junk Files from PC?

In late 2022, Birmingham, AL-based heart hospital, Cardiovascular Associates reported unauthorized access to sensitive information stored on their secured network. This led to the leakage of personal data including names, Social Security numbers, and more, of around 441,000 patients. – Source

Imagine how much data must have been leaked by hackers. Lately, there have been multiple cases of data leakage, privacy breaches, etc., that challenge our notions of data security every day.

Hackers and e-waste recyclers are always on the lookout for devices from which they could dig out “gold”. Not the metal of course, but the data on them. From financial details to personal documents, and deleted or junk files, this data is more valuable than oil or gold.

You must be wondering what hackers get out of junk files. The answer is simple: everything. Let’s try to understand junk files in detail.

Junk files Demystified

As the name goes, junk files are useless data that we delete or discard from our PC. However, sometimes, we cling on to junk files by stowing them away in a folder and forgetting about them. Temporarily, these junk files seem to have no effect on the drive.

However, in the long run, these files accumulate and start choking the drive and eating up unnecessary space. Some files also tend to get corrupted, causing performance issues with the drive. To avoid such inconveniences, you must wipe off junk files from your computer permanently.

How Vulnerable Are Junk Files?

Yes, like any other file, junk files are vulnerable to data theft. As the saying goes, ‘One man’s trash is another man’s treasure,’ these junk files are like a gold mine for data thieves. From identity- related documents to financial details and personal files, there is a lot of data that can be dug out.

Junk files also contain data, including old utility bills, browser data, and media files. You may not want them anymore, but for hackers, the information is enough to breach your privacy.

Dumpster Diving

To reach sensitive data on your discarded computer drives, people with malicious intents commonly practice what is known as ‘dumpster diving.’ As the name suggests, it is the act of salvaging useful and sensitive information, such as browser history, financial details, login credentials, and more.

Once stolen, this data can be misused to harm your privacy. This is why it becomes essential to securely erase junk files and other data from your PC.
