What is happening is that those are directories that are not empty (they still have files in them). Because they still have files in them, they cannot be removed.
The reason why all of the files were not removed from them is because the Use Time Buffer is checked in Cleaner Settings. With this checked files less than two weeks old are not deleted. This provides you protection from deleting a file in the temporary directory that may not be so temporary.
If you uncheck the Use Time Buffer checkbox, all of the files in the temporary directories and the directories will be deleted.
The directories are C:\Documents and Settings\Ronald(and some other letters)\Local Settings\Temp\History and C:\Documents and Settings\Ronald(and some other letters)\Local Settings\Temp\Temporary Internet Files
The upside down s, which actually looks like a sidewards s and is called a tilde, indicates that the directory or file name is longer than 8 characters long. In the olden days directory and file names could only be up to 8 characters long. Now they can be much longer than that but to be compatible with the old way, every directory and file has a short filename that uses the tilde to show that some letters are left out.
