Securely Deleting Data

In the following chapters, you will find out how you can use the TuneUp Shredder module to permanently

delete files, folders and the Recycle Bin and why it is important to do so.

Securely Deleting Data 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 recov-

ered afterwards. Simply use TuneUp Drive Defrag to subsequently increase the security of a nor-

mal deletion method (see How to Defragment Your Hard Disk, p. 59).

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 con-

tent 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 -> Restoring Deleted Files, p. 85).

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 and the Recycle Bin. There are three different Deletion

Methods, p. 76 and you can choose the one that suits you best.

How to Securely Delete Data

Launch the TuneUp Shredder module by going to the Gain disk space category in the Start Center and

selecting Securely delete data from the Analyze storage usage and delete data area.

Alternatively, you can start the module by going to Overview of all functions in the Start Center and select-

ing the Securely delete data entry under Hard disk.
