I have this bat file :


REM Archivo "diario_paralelo.bat"
REM Este archivo ejecuta en serie las desfragmentaciones de todas las unidades de todos los discos.

I have four physical HARD drives.
In the bat above the target is optimize with the program mydefrag.
I have many partitions and DEFRAGMENT by night
But If i do sequentally I need all the day to defragment.
So I have to execute several instances of mydefrag to get result on my working time breaking coffee.
So

Disk 0 have partitions O: and X: .
Disk 1 have partitions C: , D: , F: , H: , I: , K: , M: , N:
Disk 2 T:
Disk 3 Y:


What I would like to do is defragment at the same time O: , C: , T: and Y: .
When O: finished continue with X:
When C: finished continue with the second partition on the disk 1 and then third, sequantially.

What can i do to adapt the script ?

Best Regards

pause "to see what is happening"


With the command START all defragmentations begin at the same time.
But I need to re-group in four categories. I have four hard disk physical.


Something like this

rem first group or disk . I need first defragment O: and then X: . Not at the same time.

Not at the same time. When finish one continues with the next.

But I need two groups
