Is it the same as saying of Mr. JohnZeman?[/quote]No! I think it is not the same thing.. I guess he is saying about this
[quote="DryRiverBed"]Is this link a toggle button of two drives and ?
I want to switch about five HDD drives By sequentially change. [/quote]Yes! The code mentioned in it toggles between 2 drives only.. it toggles retaining the entire path (useful, when you have two drives with similar folder structure ..in case of backup drives)
But, it can be used at the root directory too, like in your requirement (but only 2 drives)
[quote="DryRiverBed"]At first glance,it looks very difficult for not well informed man about the personal computer.
I will try though I don't understand at all at present.
Anyway, I'll try. Thank you.[/quote]That's fine.. the code requires some modification to exactly meet your requirement.
I too, am very new to this coding stuff. But, I think I can pull this out, somehow 
Just let me know the exact drive letters you would like the button to toggle (cycle?!!) through
