Extends the volume or partition with focus and its file system into free (unallocated) space on a disk. Syntax: EXTEND SIZE= ...

Extends the volume or partition with focus and its file system into free     (unallocated) space on a disk.  Syntax:  EXTEND [SIZE=] [DISK=] [NOERR]         EXTEND FILESYSTEM [NOERR]      SIZE=    Specifies the amount of space in megabytes (MB) to add to the                 current volume or partition. If no size is given, all of the                 contiguous free space that is available on the disk is used.      DISK=    Specifies the disk on which the volume or partition is                 extended. If no disk is specified, the volume or partition is                 extended on the current disk.      FILESYSTEM  Extends the file system of the volume with focus. For use only                 on disks where the file system was not extended with the                 volume.      NOERR       For scripting only. When an error is encountered, DiskPart                 continues to process commands as if the error did not occur.                 Without the NOERR parameter, an error causes DiskPart to exit                 with an error code.      On basic disks, the free space must be on the same disk as the volume or     partition with focus. It must also immediately follow the volume or     partition with focus (start at the next sector offset).      On dynamic disks with simple or spanned volumes, a volume can be extended     to any free space on any dynamic disk. Using this command, you can convert     a simple dynamic volume into a spanned dynamic volume.      If the partition was previously formatted with the NTFS file system, the     file system is automatically extended to fill the larger partition. No data     loss occurs. If the partition was previously formatted with a different     file system than NTFS, the command fails with no change to the partition.     If the partition was not previously formatted with a file system, the     partition will still be extended.      A volume or partition must be selected for this operation to succeed.  Example:      EXTEND SIZE=500 DISK=3     EXTEND FILESYSTEM
