Permanently Deleting Data

In the following chapters, you will find out why it is important to do so and how you can use the TuneUp

Shredder tool to permanently delete files, folders and the Recycle Bin:

Securely Deleting Files Afterwards

If you deleted a sensitive file in a "normal" way, you cannot subsequently delete it with TuneUp Shredder.

However we have a tip for you:

When you defragment hard disks, any deleted files are normally overwritten and cannot be recovered

afterwards. Simply use TuneUp Drive Defrag to subsequently increase the security of a normal deletion

method (see How to Defragment Your Hard Disks, p. 24).

Permanently Delete Data - Introduction

When you delete a file, it generally ends up in the Recycle Bin. In Windows, this Recycle Bin is simply a folder

that collects files for deletion. Retrieving a file from the Recycle Bin is child's play and therefore many users

regularly empty the Recycle Bin or delete their files without sending them to the Recycle Bin, in order to feel that

the file has been securely deleted.

Note however that when you delete a file, Windows does not actually remove it altogether - its entire content

remains on the hard disk. Windows merely marks the file as "deleted" from the file system and releases the space

taken up by the file so that it can be used again. Until this disk space is used again, it is very easy to restore this

file (for example using TuneUp Utilities and the function Restore deleted files).

However, if you want to be absolutely sure that even professionals could not restore your sensitive data, use

TuneUp Shredder to irreversibly delete files, folders or the Recycle Bin. You can choose the most suitable of

three different deletion methods.
