Hello everyone,

I have a list of strings called myListOfFilePaths and I want to find 
which one of those strings ends in ".DS_Store" (a hidden file created by 
the Mac OS).  I can pick it off using Select as

	Select[myListOfFilePaths, StringMatchQ[#, ___ ~~ ".DS_Store" ~~ 
EndOfString] &]

but I can't do it using Cases or Position

	Cases[myListOfFilePaths, ___ ~~ ".DS_Store" ~~ EndOfString]

	Position[myListOfFilePaths, ___ ~~ ".DS_Store" ~~ EndOfString]

despite the fact that Head[___ ~~ ".DS_Store" ~~ EndOfString] is StringExpression.  What am I doing wrong?

	Regards,

	Gregory
