Delete Local Files that Do Not Exist on the FTP Server

See more FTP Examples

Demonstrates how to get a list of local files in a directory tree that do not exist on the FTP server. AutoIt

Local $bSuccess = False

; This example requires the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.

$oFtp = ObjCreate("Chilkat.Ftp2")

$oFtp.Hostname = "ftp.example.com"
$oFtp.Username = "login"
$oFtp.Password = "password"

$oFtp.KeepSessionLog = True

; Connect and login to the FTP server.
$bSuccess = $oFtp.Connect()
If ($bSuccess <> True) Then
    ConsoleWrite($oFtp.LastErrorText & @CRLF)
    Exit
EndIf

; Set the current remote directory to the root of
; the remote tree to be compared.
$bSuccess = $oFtp.ChangeRemoteDir("abc123")
If ($bSuccess <> True) Then
    ConsoleWrite($oFtp.LastErrorText & @CRLF)
    Exit
EndIf

; Recursively descend the local directory tree
; and find the files that exist locally but not remotely.
; These are the files what would be uploaded via
; the SyncRemoteTree method call with mode = 1.
; (Mode 1 would upload all files that do not exist on the FTP server.)

; The actual uploading is avoided by setting the preview-only argument to True.
Local $iMode = 1
Local $bDescendTree = True
Local $bPreviewOnly = True
$bSuccess = $oFtp.SyncRemoteTree2("/temp/abc123",$iMode,$bDescendTree,$bPreviewOnly)
If ($bSuccess <> True) Then
    ConsoleWrite($oFtp.LastErrorText & @CRLF)
    Exit
EndIf

; The files what would've been uploaded are now available in the SyncPreview property,
; which contains a list of local file paths, one per line.
; A program can iterate over them like this:
$oSa = ObjCreate("Chilkat.StringArray")
$oSa.LoadFromText $oFtp.SyncPreview

$oFac = ObjCreate("Chilkat.FileAccess")

Local $iNumFiles = $oSa.Count
Local $i = 0
Local $sLocalFilePath
While ($i < $iNumFiles)
    $sLocalFilePath = $oSa.GetString($i)
    ConsoleWrite($sLocalFilePath & @CRLF)

    ; An application can delete the file using Chilkat's file access object,
    ; or it can choose to use the native file API available in the programming language:
    $bSuccess = $oFac.FileDelete($sLocalFilePath)
    If ($bSuccess <> True) Then
        ConsoleWrite("Failed to delete: " & $sLocalFilePath & @CRLF)
    EndIf

    $i = $i + 1
Wend

$bSuccess = $oFtp.Disconnect()
