(CkPython) Delete Local Files that Do Not Exist on the FTP Server

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

Chilkat Python Downloads

Python Module for Windows, MacOS, Linux, Alpine Linux, Solaris

import sys
import chilkat

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

ftp = chilkat.CkFtp2()

ftp.put_Hostname("ftp.example.com")
ftp.put_Username("login")
ftp.put_Password("password")

ftp.put_KeepSessionLog(True)

# Connect and login to the FTP server.
success = ftp.Connect()
if (success != True):
    print(ftp.lastErrorText())
    sys.exit()

# Set the current remote directory to the root of
# the remote tree to be compared.
success = ftp.ChangeRemoteDir("abc123")
if (success != True):
    print(ftp.lastErrorText())
    sys.exit()

# 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.
mode = 1
descendTree = True
previewOnly = True
success = ftp.SyncRemoteTree2("/temp/abc123",mode,descendTree,previewOnly)
if (success != True):
    print(ftp.lastErrorText())
    sys.exit()

# 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:
sa = chilkat.CkStringArray()
sa.LoadFromText(ftp.syncPreview())

fac = chilkat.CkFileAccess()

numFiles = sa.get_Count()
i = 0

while (i < numFiles) :
    localFilePath = sa.getString(i)
    print(localFilePath)

    # 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:
    success = fac.FileDelete(localFilePath)
    if (success != True):
        print("Failed to delete: " + localFilePath)

    i = i + 1

success = ftp.Disconnect()
