saving a DRM book to pendrive/external disk to later download and read it on personal notebook (with Adobe Digital Editions)

[Barbyland]

Hello.

I installed Adobe Digital Editions on my mother's personal computer and activated my Adobe ID in order to be able to purchase, download and read DRM books there.

But is it possible to save the DRM books to a pendrive or external hard disk, so that I can "carry them" and later download and read them on my personal notebook (having previously installed Adobe Digital Editions and activated my Adobe ID in the notebook)?

I don't know if DRM books can be saved to pendrives and external hard disks...
