For I know not what obscure reason, Xp, Vista and Seven are able to access only the first partition on a device identified as removable.
If your device used for DidJiX is identified as such
(all are not, especially hard drives, but conventional hard drives are shock sensitive),
you can not directly copy your music on its second partition
(often called "extended" on this blog)
from your Windows.
In this case, from your computer, simply start DidJiX before your Windows system and use the file explorer Qtfm to copy your music from your hard drive to the DidJiX extended partition.
You will find your Windows hard drive and the DidJiX extended partition in the left panel of Qtfm.
Use
Win
e
keys to start Qtfm and notice that your hard drive will be read-only.
