How important is it to delete completed torrents?

I'm sorry about this, since this seems like a question that gets asked and answered often, but I tried multiple searches and couldn't find the answer.

A friend of mine told me that if I don't periodically delete torrent files (.tor files) for completed torrents and instead allow them to accumulate, I'll end up taxing my RAM dramatically.

What I like about keeping those files is that my client then has a history of all the torrents I've downloaded, so that it warns me if I'm about to download a duplicate.

It seems like I really shouldn't make the client sit on a mountain of torrents. Is there a way to configure it so that it'll tell me if I've already downloaded a client without me never having to delete a single .tor from my "Completed" folder?

As long as you remove the task from uT, the .torrent files won't actually use up RAM.

If EACH torrent added 1 MB to uTorrent's ram use, even having 100 stopped torrents would add at most 100 MB extra ram use.

Real usage by each torrent is *FAR* less than that, probably on the order of 10-100 KB extra ram used per torrent.
