How To Permanently Delete Files

We have come to use our PCs and laptops for almost every aspect of our lives. From our daily routine to keeping track of important personal information, there is a ton of sensitive data stored on our hard drive. This leads many individuals to look for ways to permanently delete files. When searching for different methods for how to permanently delete files, users need to be able to discern the difference between deleting a file and rendering it unreadable.


Deleting vs. Erasing

Ironically both descriptions are basically erroneous. When the average user thinks of deleting files, they think of a recycle bin then going into the recycle bin and deleting the files from there. The problem is that this does not delete files permanently. To permanently delete files from a hard drive, you need to overwrite the data contained in the files. Unless the software you are using replaces the “deleted” file’s data with new data, the file hasn’t been deleted.

To better understand this, it is imperative that users understand that when you press “delete” on your keyboard, you are only letting the operating system tag the space used for the file to be available to be overwritten. The file is not permanently  deleted until the data of the file is overwritten with new data and the old data rendered unrecoverable.


Using file deleting software

The best answer on how to permanently delete files from computer is to use hard drive erasure software. One of the reasons this software is so helpful is because it allows the user to specify the data that will be deleted by file type, location or associated activity, and then further specify the degree to which the data will be overwritten with new data.
