FTP does not support directory downloads, but FTP commands provide the mget command, allowing multiple file downloads, but each download a file needs to be confirmed, can not be automatically completed. This article mainly introduces the use of batch processing, combined with FTP related commands to achieve batch file download, in order to achieve the purpose of directory download.
The general idea is as follows:
Ftp-s: filename hosts >result. TXT executes the script and outputs the results to result. Txt
Script content, such as
CD Mydir
Ls
Bye
You can list the Mydir commands
You then use batch processing to parse result. Txt
From the Opening ASCII mode data connection for file list. The next line starts counting, until the Transfer complete are all content to download
Then use the batch process with the FTP script, download one by one using the Get command
But the actual process found that in the FTP script to use get has a problem, the hint parameter error, cannot be used.

TransfersFilesTo and from a computer running a FTP Server service
(Sometimes called a daemon).FTP can be used interactively.
FTP [-v] [-d] [-i] [-n] [-G] [-S: filename] [-A] [-W: windowsize] [-A] [host]
-v suppresses display of remote server responses.
-N Suppresses auto-login upon initial connection.
-I. TurnsOffInteractive prompting during multiple file
Transfers.
-D Enables debugging.
-G disables filename globbing(GLOBCommand).
-S: filenameSpecifies a text file containing FTP commands;The
Commands would automaticallyRunAfter FTP starts.
-AUseAny local interfaceWhenBinding Data Connection.
-A login as anonymous.
-w : buffersize Overrides the default transfer buffer size of 4096 .
host Specifies the Host name or ip address of the remote
host to connect to .
Notes:
- mget and mput commands take y / n / q for yes / no / quit .
- use control-c to abort commands . /span>
I found that the-I parameter can remove mget hints and, after testing, implements the following script (using anonymous login, if not anonymous, you can modify the login script):
echo cd autoruns>ftp. Txt
echo mget *>>ftp. Txt
echo bye>>ftp. Txt
Ftp-i-a-s: FTP. TXT 10.1. 103.10
However, this only downloads the files in the directory, if there is a subdirectory, it also needs to use the dir command output, and to the output to the text, use Find to extract the directory, such as:
Echo cd autoruns ftp . TXT
echo dir >> ftp . TXT
echo bye >> ftp . TXT
ftp -a -s : FTP . TXT&NBSP 10.1 . 103.10 | Find " <dir> " " result . TXT
for / f " tokens=2,3* " %%i in ( result . TXT ) do echo %%k
If you have subfolders, you need to write them down in depth.
After writing the test, implement the following script, run the environment WinXP SP2, run through, not on other systems tested:
1, the main script ftpget.bat, change the first 4 variables related information, the script calls Maketree.bat, see 2
RemFTP server address
SetHost=10.1.103.10
RemFTP login name, if anonymous do not change
SetUser=Anonymous
RemFTP login password, if anonymous do not change
SetPass=123456
RemNeed to download the FTP directory, if you download subdirectories to the grid

del result%treetime% . TXT
del ftp%treetime% . TXT
Although it has been implemented, but there is still a small problem, that is, mget *.* can not download the program without extensions, if the use of Mget * can download all files, but will be the directory files are also downloaded. Get the error in the FTP script does not know why.
