It's not clear what you're trying to achieve.
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. ;)
