Step 2. Right-click on this file. Two new options appear on the pop-up menu, Erase and Eraser Secure Move as follows:

We are going to use the Erase option to permanently delete this file.

Step 3. Select the Erase item from the menu, as shown in Figure 1 above.

The Confirm Erasing pop up dialog box will appear as follows:

3.1 How to Wipe Unused Disk Space

Erasing unused disk space involves wiping all traces of previously existing files from the 'empty space' of your hard drive/portable storage device. This empty space usually contains files that were not deleted properly (please refer to the Recuva Hands-on guide and the How-to Booklet Chapter 6 from more information about this).

Step 1. Select Start > Programs > Eraser > Eraser

Tip: You can perform the wiping task on demand or you can schedule it to occur at a specified time.

Important: This process could take between 2 and 5 hours to complete and will slow your computer down while it operates. It maybe a good idea to run or schedule the free space wipe when you are not using your computer (or have gone home/to bed for the night).

3.2 How to use the On-Demand Task

To create an On-Demand task for wiping unused disk space, perform the following steps:

Step 1. Click

Step 2. Select File > New Task as follows:

Figure 3: Selecting a New Task in the File menu

The Unused space on drive option should be selected.

Step 3. Choose the drive you want to clear the free space on. (In this example, the Local Disk (C:) has been selected. This is usually the primary hard drive on most computers.)

3.3 How to Use the Scheduler Feature

Since we may not always remember to do this kind of computer 'housekeeping', Eraser has an option that lets you schedule a wiping task so that it runs at an appointed time every day, or one day per week.

Step 1. Click in the Eraser main screen.

Step 2. Select File > New Task as follows:

Figure 8: Selecting a New Task in the File menu

This will activate a window similar screen to Figure 4 (in which you created an on-demand task).

Step 3. Set these options as outlined in section 3.2 How to Use the on-Demand Tasks Option.

Step 5. Select day or event item that best suits your needs from the Every drop-down list.

Step 6. Enter the time that best suits your needs in the At timer, which can only be entered in a 24-hour format.

Step 7. After you have set a time and day, click .

The scheduled task will appear as follows:

Note: The computer must be switched on for the scheduled task to run.
