But it is a relative waste of memory to create strings for every file name in the bundle, especially since those are not what are returned to the caller (URLs are). So, an idea: cache the existence of the most common file names (Info.plist, en.lproj, etc) instead of creating entries for them. If other resources are requested, then go ahead and do the readdir and cache the rest of the file names.
