To create a new Plus D disk image
On the File menu, click New.
In the dialog box, click the Plus D disk image (.mgt) icon.
Enter a name for the file.
Choose a location for the file and click OK.
On the resulting dialog box, choose which drive to insert the new disk image into and click OK.
Tip
Click the Format disk checkbox when creating disk images to avoid having to format disks using G+DOS first.
You can also use the shortcut key Ctrl+N to create a disk image.
If the Plus D disk drives window is hidden, click Disk Drives on the View menu to see which disk images are in which drives.
