FtpCreateDirectoryA function (wininet.h)

Creates a new directory on the FTP server.


BOOLAPI FtpCreateDirectoryA(
  HINTERNET hConnect,
  LPCSTR    lpszDirectory



Handle returned by a previous call to InternetConnect using INTERNET_SERVICE_FTP.


Pointer to a null-terminated string that contains the name of the directory to be created. This can be either a fully qualified path or a name relative to the current directory.

Return value

Returns TRUE if successful, or FALSE otherwise. To get a specific error message, call GetLastError. If the error message indicates that the FTP server denied the request to create a directory, use InternetGetLastResponseInfo to determine why.


An application should use FtpGetCurrentDirectory to determine the remote site's current working directory instead of assuming that the remote system uses a hierarchical naming scheme for directories.

The lpszDirectory parameter can be either partially or fully qualified file names relative to the current directory.

Like all other aspects of the WinINet API, this function cannot be safely called from within DllMain or the constructors and destructors of global objects.

Note  WinINet does not support server implementations. In addition, it should not be used from a service. For server implementations or services use Microsoft Windows HTTP Services (WinHTTP).


The wininet.h header defines FtpCreateDirectory as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
