Due to low data cap and doing very customized installs I've generally
purchased DVD sets {now available on a single flash drive}. The one I
purchased has ISO's of both install and live versions on a single partition.
I wish to copy only the install DVDs to a single partition of:
1. the laptop's internal drive.
2. another USB connected device.
In the past dd has been convenient and appropriate.
This time I want only some of the files in the source directory.
I could use Caja or rsync if my only criteria was minimal keystrokes.
Thinking about this has prompted questions.
1. Using Caja or rsync -- are there options to minimize transfer time.
2. Can I do casual web browsing and email reading at the same time.
3. Can I take advantage of my processor having 2 or more cores.
I suspect I'm asking if Debian does multi-tasking &/or multi-threading.
That question implies I what should I be reading.
TIA
