ange-ftp-re-read-dirange-ftp-re-read-dir is an alias for `ange-ftp-reread-dir' in `
ange-ftp.el'. (ange-ftp-re-read-dir &optional DIR) Reread remote directory DIR to update the directory cache. The implementation of remote FTP file names caches directory contents for speed. Therefore, when new remote files are created, Emacs may not know they exist. You can use this command to reread a specific directory, so that Emacs will know its current contents.
