OK I got it.

who knows.

Hi ...

You can easily see the size of a directory by right-clicking on a folder in
windows and choosing properties ... or take the equivalent keyboard route and
press "Alt Enter". Mine says all 3+4+5 men tb's total 7.05 GB ... It took me
quite some time to download them all at ~55kB/s using ADSL :)

Groetjes,
Paul
