 3. To add a file wrapper to existing wrapper use `-addFileWrapper` or `-setFileWrapper`, the difference between the two being that add will suffix a filename with a 2, 3, 4, etc… if the file exists already and return the final filename, set will overwrite an existing one. `-addContent` and `-setContent` work the same way, but create the file wrapper for you.
 4. To remove a file wrapper from existing wrapper use `-removeFileWrapper`.
 5. To retrieve contents of a regular file wrapper use one of various convenience methods: `-data`, `-string`, `-dictionary`, `-image`.
-6. To get wrappers from a directory wrapper use `@property fileWrappers` or call `-fileWrapperWithPath`.

To write the wrapper to disk call `-writeToURL` or `-writeUpdatesToURL`, the difference between the two being that updates will update the wrapper location, so use this only in situations like autosave for duplicate operations use `-writeToURL`. If the write is issued as part of NSDocument's save routine there's a convenience method `-writeToURL forSaveOperation` that automatically calls `-writeToURL` or `-writeUpdatesToURL` based on save operation and also handles document backups, url switches on save as and is app sandox ready.
