Hi Joost, thanks fpr your posting! :) Ok...another USB drive mau lay around here...will see... Just two quick questions: Is this ok, to preserve as much as possible of the settings/attributes/whatever of the files or do you anything better and quickier than this: (cd <sourcedir>/. ; tar cf - . ) | ( cd <targetdir>/. ; tar xvpsf - ) ?
