Question: Deleting planet data

I recently reinstalled entropia and noticed thatmy download status for other planets have some values, for example Toulan 65%.

Does this mean that i have downloaded 65% of Toulan, if so is there anyway i can delete this? (as i would rather have the space on my hard disk until the point for travelling there).

Or is this just some common files?


thanks for any help, would love to free up some HD space if possible (only 80 GB hard drive in my machine :ahh:)
