That was right.

HoweverI found tricky technique to use pkg functions form CD-ROM.
The keyword is 'subst command'.

******************
Z:\bin>subst /?
Associates a path with a drive letter.

SUBST [drive1: [drive2:]path]
SUBST drive1: /D

  drive1:        Specifies a virtual drive to which you want to assign a path.
  [drive2:]path  Specifies a physical drive and path you want to assign to
                 a virtual drive.
  /D             Deletes a substituted (virtual) drive.

Type SUBST with no parameters to display a list of current virtual drives.
******************************


The following the record what I did.
********
By the exploerer I copied all installed MSVC-Octave to E:\Octave-2.9.13
Drive E: is the USB HDD for my computer.
***Folder structure
E:\Octave-2.9.13\bin
E:\Octave-2.9.13\doc
E:\Octave-2.9.13\include
     :
     :
*******
I exectuted cmd.exe and goto E:\ by >e:

E:\>Subst z: e:\Octave-2.9.13
E:\>z:
Z:\>cd bin
Z:\bin>octave

Then octave was executed.
octave> pkg uninstall all
octave> pkg prefix z:\share\octave\packages

octave> pkg rebuild windows
octave> pkg rebuild time
octave> pkg rebuild symbolic
octave> pkg rebuild struct
octave> pkg rebuild strings
octave> pkg rebuild statistics

octave> pkg rebuild sockets

octave> pkg rebuild fixed
octave> pkg rebuild econometrics
octave> pkg rebuild control
octave> pkg rebuild communications
octave> pkg rebuild combinatorics
octave> pkg rebuild audio
octave> pkg rebuild arpack

octave> pkg load all
octave> exit


The all files were copied by exploerer usinf XP facility.
For my computer CD-ROM drive d:

***Folder structure
D:\bin
D:\doc
D:\include
     :
     :

Then I loged off the computer and logged on again to reset subst.
(Pherhaps it can be replaced by 'subst z: /D')

The cmd was executed again.
>d:
D:\>subst z: d:\
D:\>z:
Z:\>cd bin
Z:\bin>octave

  :
octave> pkg list

Package Name       | Version | Installation directory
-------------------+---------+-----------------------
           arpack *|   1.0.1 | z:\share\octave\packages\arpack-1.0.1
            audio *|   1.0.1 | z:\share\octave\packages\audio-1.0.1
    combinatorics *|   1.0.2 | z:\share\octave\packages\combinatorics-1.0.2
   communications *|   1.0.2 | z:\share\octave\packages\communications-1.0.2

**********************
Of course, in my case,  a drive letter 'z' should not be used. 
But there perhaps is to be at least a usable drive name.

In cd-rom, it's better for you write a proper batch file for booting octave 
easily.
