If you want to delete your files permanently, you’ll want to make sure no software can recover the data.
PC FILE SHREDDER HOW TO
How to Permanently Delete Files from the Computer?

Then it stores a new series of 1.s and 0’s over the old one. Thus, instead of the computer going and erasing all the 1’s and 0’s, it waits until there’s something new to store.
FAT allocates that space as free space, ready to be written over. When you delete a folder or a file and remove it from the recycle bin, all what you’ve done is instruct the FAT to remove pointers to the data. FAT also protects written data so the computer can’t write over used space. FAT organizes all data bits in an orderly fashion. It’s the FAT that tells your computer system where the file is located on the drive. The saved file is then written on another section called the File Allocation Table (FAT). If the file is too big for one section, the computer may break the file into multiple sections. In SSD and USB drives, the bytes are stored in a series of individual memory cells rather than long bands.įor speed and efficiency, the computer writes the data in the first available space it can find that’s sizable enough to hold the file. These bits of data are written in long continuous bands and saved around the physical hard drive. Your hard disk writes every byte of information you create as a series of blocks represented by 1’s and 0’s. How Does Data Storage Work In The Computer? To understand how deleting data works, let’s first understand how data storage works in a computer. For Solid-State Drives (SSD), the data is removed permanently when you delete files and folders. However, this only applies to regular Hard Disk Drives (HDD). Until your OS overwrites the hard drive sector, a file recovery program can scan, find, and restore the deleted files. Thus, for fast operations, the OS will only delete the pointer and then later overwrite the deleted data with new information.Īs you continue creating new files and folders, the OS overwrites the sections of the hard drive that have no pointers that indicate the existence of data. The reason the OS only deletes the pointer is because it takes much longer to delete a file than it takes to delete the pointer. So the data still exists in a sector of your hard drive, even though the system shows the data no longer exists. I did not uninstall McAfee, only disabled McAfee features in the software.Whenever you delete any file, what you’ve essentially done is delete the tracker pointing to the file.
PC FILE SHREDDER UPDATE
Had to disable McAfee features for a Windows 10 major update to proceed once (maybe 1709 major update?). I've used McAfee software since 2012 (on my 2012 Dell desktop) with only 1 problem. I looked at some of the Amazon McAfee reviews some computer owners are incapable of maintaining their computers (software, hardware) do so at your own risk. / Current McAfee website mentions 'shredding sensitive files' (under the multi-faceted privacy protection section). I usually buy a Key Card from Amazon and download McAfee software from McAfee website. I shred files occasionally.Īmazon currently sells McAfee Total Protection for 3 devices 2020 for less than $22, uses Amazon download services once installed might want to turn OFF Auto-Renew ($79.99). Can select 1, 42, or whatever number of files you want shredded. Choices are Basic (shreds twice), Safe (shreds 5 times), or Complete (shreds 10 times). Shredder permanently deletes files so they can't be recovered. Currently have McAfee Total Protection which includes Shredder. I've used McAfee products since 2012, which I believe all had a Shredder program included.
