In what way does the LIKE operator not do what you want?
The concern I would have would be if his "newFullPath" variable
contains characters which would be interpreted by the LIKE
operator as wildcards. It's not as uncommon as one might guess
that a file path contains "*" or "?".
You can escape the wildcards...
That's not actually documented on the Predicate Format String Syntax
or BNF Definition of Cocoa Predicates pages. There's something about
escape sequences for numbers, but not about string contents. I
suppose it's likely that escapes are supported for meta-characters.
I suppose some trial and error would reveal if it works. I'm not
that invested. ;)
