How to correctly configure Julia portable or stanalone, For everything to happen from the external storage USB drives: Add, update packages ? In Julia's helps is there any procedure?

All you need to do is to configure your JULIA_DEPOT_PATH. This is the place where Julia is installing it's packages and holding pre-compiled codes.

Assume your installation (USB drive) is D:\ and you unzip Julia to D:\Julia1.5.0

mkdir D:\JuliaPkg1.5.0
set PATH=D:\Julia1.5.0\bin;%PATH%
set JULIA_DEPOT_PATH=D:\JuliaPkg1.5.0
julia

Now you are ready to install the packages etc.

The final solution is the following: File batch windows

@echo off
set myDIR=%~d2\SA_Ptbls\julia-1.5.0-win64
if not exist %myDIR% (mkdir %myDIR%)
set PATH=%~d2\SA_Ptbls\julia-1.5.0-win64\julia-1.5.0\bin;%PATH%
set JULIA_DEPOT_PATH=%~d2\SA_Ptbls\julia-1.5.0-win64
julia

% ~ d2 gives you the current drive letter when connect the USB drive to another computer (the drive letters change!!!)
if not exist% myDIR% (mkdir% myDIR%) checks if the subdirectory exists, if it does not exist it creates it

When executing the batch file, we successfully obtain:

And to run the batch file from a shortcut. After creating the shortcut it was configured as shown:

I did not achieve that in the status bar when executing the batch file the Julia icon was shown; and instead shows the WindowsPowerShell icon:
