Directory Existence Check

How to test if a directory exists on an FTP server.

A good way to check to see if a directory already exists is to try to "cd" to that remote directory by calling ChangeRemoteDir. If it succeeds, then the directory exists. If not, then it does not exist. An alternative method is to set the ListPattern = "*" and then iterate over the files/directories, looking for the directory.

set ftp = CreateObject("Chilkat.Ftp2")

'  Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial")
If (success <> 1) Then
    MsgBox ftp.LastErrorText
    WScript.Quit
End If

ftp.Hostname = "ftp.chilkatsoft.com"
ftp.Username = "***"
ftp.Password = "***"

'  Connect and login to the FTP server.
success = ftp.Connect()
If (success <> 1) Then
    MsgBox ftp.LastErrorText
    WScript.Quit
End If

'  Does the "temp" directory exist?

dirExists = ftp.ChangeRemoteDir("/temp")
If (dirExists = 1) Then
    MsgBox "Yes, the temp directory exists."
    '   Yes, it exists. Restore the current remote dir:
    success = ftp.ChangeRemoteDir("..")
    If (success <> 1) Then
        MsgBox ftp.LastErrorText
        WScript.Quit
    End If

End If

'  Alternatively, you may set the ListPattern = "*" and
'   look for the directory:
ftp.ListPattern = "*"

n = ftp.NumFilesAndDirs
If (n < 0) Then
    '  Failed to get directory listing based on ListPattern
    MsgBox ftp.LastErrorText
    WScript.Quit
End If

foundDir = 0
If (n > 0) Then
    For i = 0 To n - 1

        isDir = ftp.GetIsDirectory(i)
        If (isDir = 1) Then

            fname = ftp.GetFilename(i)
            If (fname = "temp") Then
                MsgBox "Found temp directory!"
                foundDir = 1
                Exit Do
            End If

        End If
