i tried moving multiple items and there's was filename conflict for one of the them,i clicked the windows popup to skip the operation for this file,the other files were moved, then i noticed that the operation wasn't recorder in the undo list, i'm using Win 7 64-bit

Yes, that's actually a problem with shell copy. If only a single file was skipped it returns fAnyOperationsAborted = True, but it does not tell me if any operation was not aborted. So I have to guess, and I decided to assume the most common case is that the whole operation was aborted if fAnyOperationsAborted = True. And an operation that was aborted is not added to the undo log.

To avoid this simply enable Custom Copy which is XY's own copy operation and does not know such problems.
