How to Shred Files?

PCBooster Free File Shredder is able to permanently shred all kinds of your unwanted files as well as folders. They can be audio files, videos, images, programs, documents, texts... whatever files you want to eliminate for good. The professional shredder tool also helps thoroughly wipe your recycle bin to make sure all the deleted stuff can't be retrieved back by all ways, even with the most powerful recovery tool.


How to Use PCBooster Free File Shredder to Shred Files?

Step 1Choose File Option

Launch PCBooster Free File Shredder and choose "File" from options of 3 kinds of objects to delete: File, Folder & Recycle Bin for example.


Tip: usually we use Delete to remove files or folders to the Recycle Bin, then empty it; or just press Shift + Delete. Our file shredder can shred both files, folders (subfolders included) as well as erase the data in your Recycle Bin.

Step 2Select Files to Erase

Click "Next" to go to the second step. Click "Add..." to choose one or more files you need to erase. Click "Open" and the selected files will be displayed in the "Files" pane. Click "Remove" or "Clear" to remove one or all selected files from the pane.


Tip: you can erase files of any types. So check the file name, location and size of the files you want to delete because once you shred them, there is no chance to get them back.

Step 3Choose Erasing Method

There are 3 ways to delete the file.

Quick delete - Overwrites the files with pseudorandom data

Secure delete in accordance with DoD 5220.22-M - Deletes files in compliance with US Department of Defense regulation DoD 5220.22-M

Secure delete, Gutmann method - Deletes files using the method developed by Peter Gutmann. This method is considered extremely secure, but is comparatively slow.

Choose one of the methods to delete the file.

To customize the number of deletion times, you can click the button to increase/decrease the number. You can also directly enter a figure to specify the number of repeats (the bigger the number, the smaller the chance of recovery). Click "Next" to start erasing.


Tip: why should you shred files? Maybe you have deleted your files and thought no one could access them, but the truth is you are wrong in that particular thinking. There are tons of software that can bring them back to your hard drive. So if you have something that you want unrecoverably gone, you should use a file shredder.
