copyAllTo: does not do what its comment says: '/tmp/toto/titi' asFileReference ensureCreateDirectory. '/tmp/dest' asFileReference ensureCreateDirectory. '/tmp/toto' asFileReference copyAllTo: '/tmp/dest' asFileReference 'toto' directory is not copied contrary to what wrote the method comment. What is wrong, the comment or the method? Hilaire copyAllTo: aResolvable "Performs a deep copy of the receiver, to a location specified by the argument. If the receiver is a file, the file will be copied; if a directory, the directory and its contents will be copied recursively. The argument must be a reference that doesn't exist; it will be created by the copy." -- Dr. Geo http://drgeo.eu
