Check if a directory exists before making it

2010-04-14 10:36

I am using WinSCP to upload edi-files to an FTP-server with customer number as a subfolder. So my script could look like this:

option batch on
option confirm off
lcd C:\my_local_files
mkdir 123456
put .\123456\orderconf_1234.xml ./123456/orderconf_1234.xml
exit

If the folder 123456 already exists, WinSCP gives the error:

Error creating folder '123456'.
Can't create directory: File exists

The thing is that I don't know whether this folder exists or not on the FTP server, and I don't wan't WINSCP to raise an error if I try to make a folder that already exists. What is the best approach to "fix" this?

Can I with WinSCP say that "only do mkdir my_folder if my_folder doesn't exist" on the remote system?

Please read documentation:

If that does not help, come back.

Same problem while using mkdir if folder already exists

2011-06-29 15:28

Hi Martin

I am using C# to upload files at a folder but if I need to create folder but mkdir command produces error if a folder already exists at FTP server.

Please let me know how can I check its existance at FTP server before creating it.

Thanks in advance

Needing more clarification after review your link

@martin The example you provide uses JavaScript while I have used some JavaScript the coding is not familiar to me.

My issue is during an automated process I want to check and see if a folder exists on a remote computer and if it does write a file to it.

If it does not mkdir a folder and then write the file.

IF EXIST (winscp.com /command "option batch ""off""" "option confirm ""off""" "open ""NAA_FTP_TSL""" "cd Pervasive\Production\test\concentra\" "exit") (
winscp.com /command "option batch ""off""" "option confirm ""off""" "open ""NAA_FTP_TSL""" "cd Pervasive\Production\test\concentra\" "lcd ""C:\Users\naa\Cosmos9_Work\Production\concentra\work\""" "put ""elig_test.20120813.txt""" "exit"
) ELSE ( 
winscp.com /command "option batch ""off""" "option confirm ""off""" "open ""NAA_FTP_TSL""" "mkdir Pervasive\Production\test\concentra\" "exit"
)

-or-

rem %1 is local directory
rem %2 remote directory
rem %3 is file name
pause
cd "c:\Program Files (x86)\WinSCP"
pause
winscp.com /command "option batch ""off""" "option confirm ""off""" "open ""NAA_FTP_TSL""" "cd ""%2""" "lcd ""%1""" "put ""%3""" "exit"
pause
echo %errorlevel%
pause
rem IF 2 GEQ 15 echo "bigger"
IF %ERRORLEVEL% == 0 (
   Echo No error found
   GOTO exit
} ELSE (
   GOTO error
)
 
echo.errorlevel = %errorlevel%
pause
 
GOTO exit
rem winscp.com /command "option batch ""off""" "option confirm ""off""" "open ""NAA_FTP_TSL""" "lcd ""C:\Users\naa\Cosmos9_Work\Production\jacob\""" "cd ""Pervasive\Production\test\""" "put ""test1.map.xml""" "exit"
 
:error
pause
 
winscp.com /command "option batch ""off""" "option confirm ""off""" "open ""NAA_FTP_TSL""" "mkdir Pervasive\Production\test\concentra\" "exit"
winscp.com /command "option batch ""off""" "option confirm ""off""" "open ""NAA_FTP_TSL""" "cd ""%2""" "lcd ""%1""" "put ""%3""" "exit"
 
pause
 
:exit

@AlphaUno: I'm sorry, but this is not a programming forum.

Alternatively you can use .NET assembly, if that helps:

Searching existing folders in SFTP server

2012-09-25 07:18

This is how use my WinSCP to access SFTP server.

Dim startInfo As New ProcessStartInfo
startInfo.FileName = uWinScpPath
startInfo.RedirectStandardInput = True
startInfo.RedirectStandardOutput = True
startInfo.UseShellExecute = False
startInfo.CreateNoWindow = True
startInfo.WindowStyle = ProcessWindowStyle.Hidden
 
''Start WINscp
Dim process As New Process
process.StartInfo = startInfo
process.Start()
 
''run the commands 
''Open sftp connection with User and Password validations
process.StandardInput.WriteLine("open " + _Host)
process.StandardInput.WriteLine(_UserName)
process.StandardInput.WriteLine(_Password)
Dim ans = process.StandardOutput.ReadLine
While ans <> Nothing
   If ans.Contains("Session started.") Then
         ans = ans
        Exit While
  End If
  ans = process.StandardOutput.ReadLine
End While
process.StandardInput.WriteLine("cd " + uDestPath)

From the above process, I create sub directory, copy file to it, and delete the file.

But how can I check if a subdirectory/folder in that SFTP site exists?

Thanks!

If you are using VB.NET, use WinSCP .NET assembly instead of interacting with WinSCP scripting interface directly.
https://winscp.net/eng/docs/library
The assembly has Session.FileExists method.

I think we both have the same issue.

Able to do

1. create a directory
2. move files to that directory

Unable to do

1. Check to see if directory exists
2. if it exists move files to it.
3. If it doesn't exist then create dir and then move files to it.

In case you stumble upon this from the google, the Session.FileExists(path) command works for directories as well. :)

Using remote command programm

2015-03-16 14:55

Have you tried using the remote command possibilities? E.g.:

call bash -c "[ -d <Path to directory> ] || mkdir <Path to directory>"

C# // Check & create remote directory

2021-07-13 13:48

// Check & create remote directory
if (!session.FileExists(dirTo))
{
    string[] ss = dirTo.Split('/');
    string curdir = "";
    foreach(string s in ss)
    {
        curdir += '/' + s;
        if (!session.FileExists(curdir))
            session.CreateDirectory(curdir);
    }                        
}

Can't you use option batch continue like so? I'm guessing they were trying to not use .NET

option batch on
option confirm off
lcd C:\my_local_files
option batch continue
mkdir 123456
option batch on
put .\123456\orderconf_1234.xml ./123456/orderconf_1234.xml
exit
