To prevent sensitive data from being recovered after you delete it, you can use

BitDefender to permanently delete that data by physically removing it from your

hard disk.

To permanently remove files, follow these steps:

1. Click Shred Files.

2. Follow the three-step guided procedure. For more information, please refer to

“File Shredder Wizard” (p. 106).

14.2.6. Defragmenting Hard Disk Volumes

When copying a file exceeding the largest block of free space on the hard disk, file

fragmentation occurs. Because there is not enough free space to store the entire

file continuously, it will be stored in several blocks. When the fragmented file is

accessed, its data must be read from several different locations.

File fragmentation slows down file access and decreases system performance. It

also speeds up the wear of the hard disk.

To reduce file fragmentation, you must defragment the disks periodically. Disk

defragmentation physically reorganizes the data on the hard disk so that the pieces

of each file are stored close together and continuously. It also attempts to create

larger free space areas in order to prevent files from being fragmented later.

It is recommended to defragment the hard disk in order to:

⚫ access files faster.

⚫ improve overall system performance.

⚫ extend hard disk life.

To defragment the hard disk, follow these steps:

1. Click Defragment Disks.

2. Follow the three-step guided procedure. For more information, please refer to

“Disk Defragmenter Wizard” (p. 88).

Note

Defragmentation may take a while since it involves moving portions of stored data

from a place to another on the hard disk. We recommend you to perform

defragmentation when you are not using your computer.
