I have a lot of documents that people download from my site. They are in the /download folder on the server. When people do a search for bonsai care sheets they get a list that includes a lot of mine. The funny thing is, for some reason, the URL is not correct but when you click on it, you still get my download.

This is what the incorrect URL looks like:

www.bonsaitoolchest.com/downloads/cotoneaster.pdf

On my server there is no "S" at the end of "download", yet when you click on the link, it automatically changes the URL to the correct spelling. Is this normal??

There is no folder on my server with /downloads, only /download.
How does Google come up with /downloads???
