We often delete files and folders from our PC and Mac’s hard drives. The most common way to do so is to use the ‘Delete’ setting/button on your PC or Mac. You select the file(s) you wish to delete and then press Delete to send it over to Recycle Bin (Windows) or Trash (Mac). Then you clear the Recycle Bin/Trash and the file vanishes making you believe that the deletion is done.

In reality, the file(s) your deleted files are still present on the system and can be recovered easily with the help of a data recovery software. In this blog post, you will look at the myths surrounding deletion of files from Windows PC and Mac and then discover how you can permanently erase these file(s) beyond any scope of recovery.

Myths about file deletion

Deleting files and folders using PC or Mac built-in settings doesn’t delete them permanently. Your operating system just erases the address of those files and allows those addresses to store new files. The old files are still there, it’s just that they are not available for immediate view.

 A data recovery software (even the free ones available online) can easily recover those deleted files and render your deletion effort worthless. Only a reliable file erasure software can permanently erase these files and ensure that the deleted files cannot be recovered. Before learning more about the benefits of a file erasure software, let us first understand the importance of permanent file erasure.

Why you should permanently erase your files?

When you temporarily delete your data (using your PC or Mac’s delete settings) you expose your data for unauthorized use. Anyone who gets hold of your PC or Mac can access your personal information from the residual data on the system. The personal information can include your banking details, social media credentials, social security number, personal photos and videos, etc. Any unsolicited use of this information can cause you unnecessary emotional and financial distress. To prevent such mishaps, you should erase your files permanently and the only way to do permanent erasure is by using a file erasure software.
