spiffycal2.cur and search engine crawlers

People using ZenCart are told to re-name the admin folder as a defense against getting hacked. Today I noticed that a web-crawler had hit a file on my site while indexing it for a search engine. The file that they hit on is called "spiffycal2.cur". (for the calendar)
I then did a websearch on that file name using that search engine and I get many hits all of which clearly show the name of the admin folder of people using ZenCart.
I don't see any current forum messages about spiffycal2.cur although there are some posts arcived but not relating to this issue.
My point is that re-naming the admin folder to something unique isn't going to provide any extra security if crawlers index it into the search engines.
Just a suggestion that everyone running a store try doing a search on your store's name plus the file "spiffycal2.cur" and see if your re-named admin folder is listed for everyone to see.

Also note, I have had many crawlers on my site and this issue just now surfaced. I believe it came to light as I recently did my first "salemaker" and used the spiffycalendar to set the dates.
