Pathnames are parsed by the client, including quotings and their evaluation. I would suspect that a server should get the pathname as string, without quoting. So first of all you should check which FTP client you are using. This is always a sensible problem under w32. Emacs did point to trustworthy ftp clients under w32 for years, now it expects the standard Windows ftp.exe to be mature (see <http://www.gnu.org/software/emacs/windows/faq8.html#ange-ftp>). More general, quoting pathnames in an FTP client doesn't seem to be specified as expected in the standards. RFC 959 regards pathnames just as strings: Pathname is defined to be the character string which must be input to a file system by a user in order to identify a file. Pathname normally contains device and/or directory names, and file name specification. FTP does not yet specify a standard pathname convention. Each user must follow the file naming conventions of the file systems involved in the transfer. Implicitely, one could assume that a string can be embedded in double quotes (as the usual definition of strings). This is used also for responses like 257 defined in that standard. But the practice of ange-ftp, escaping special characters by back spaces, seems to be also in use. The only place in the standard discussing pathname quotes is the case where a pathname in a response contains a double-quote ("). Then it is required to double the double-quote. Not satisfactory at all. ange-ftp is aware of this problem. The corresponding function, `ange-ftp-quote-string´, contains the following comment: ;; This is said to be wrong; ftp is said to need quoting only for ", ;; and that by doubling it. But experiment says this kind of quoting ;; is correct when talking to ftp on GNU/Linux systems. One could change the implementation of this function, but I have no idea whether other ftp clients will be broken then. Maybe one needs a customer option in ange-ftp for how to quote pathnames.
