:) But note the latter part of the sentence: "this method should only be used if the file is guaranteed to exist _for the duration of the data object’s existence_." So if I create an NSData with dataWithContentsOfMappedFile and then the user deletes the backing file, then what? I just tried in a little test app: open(), dataWithContentsOfMappedFile, breakpoint, rm file, access the NSData. Seems to work. Sean
