. Instead, you'll get an instant snapshot of the free and used memory at that time (Figure 3).Figure 3:free the output of the command is straightforward.Of course, you can make it easier for users by adding the-M option for free, as follows: Free-m. This will report memory usage in megabytes (Figure 4).Figure 4: Output the free command in an easier-to-read format.Of course, if your system is even remotely modern, you might want to use the-G option (

. The selected files are copied to the disc. After the disc burning is complete, the disc burner tray will open and the disc can be removed. You can now use the disc on another computer or in a CD or DVD player. This type of disc does not need to be closed. Tips If you decide not to burn the files to a disc, you can delete the temporary files to recover your hard disk space. To delete a temporary file, open the disc folder, and then click Delete temporary fileon the toolbar.
