How many people realize how much space is used by Preview. When it previews it doesn't read the existing file, it start a separate preview file. That stays in Incomplete indefinitely it seems, and can use up Gigabytes. You have to know to delete the previews from Incomplete. Limewire should automatically delete each preview when it's finished.

or u could do it urself u lazy bum!

To overcome that issue, I launch directly from the indirect folder of the LW Library window. That doesn't create preview files. Yes ... preview files take up space & you need to delete them after you preview or finish the download otherwise. So launch directly from incomplete folder & you won't suffer that issue.
