Reinitialize command is similar to Windows "Format" command. However it provides an easier way than "Format" command. This command will delete all data on a virtual disk and automatically format the disk with disk's file system settings, including creating custom folders. Moreover, Reinitialize command will release physical memory occupied by the virtual disk when Dynamic Memory Management feature is enabled.
To reinitialize a virtual disk, click the disk that you want to reinitialize in the disk list to highlight it. Then click on the icon button in the command toolbar to reinitialize this virtual disk.
