FTP Sync Download Tree w/ Must-Match Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the download direction, but only for files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

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.something.com"
$oFtp.Username = "my_login"
$oFtp.Password = "my_password"

; 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 tree to be downloaded.
$bSuccess = $oFtp.ChangeRemoteDir("/subDir1")

EndIf

; Possible synchronization modes are:
; mode=0: Download all files
; mode=1: Download all files that do not exist on the local filesystem.
; mode=2: Download newer or non-existant files.
; mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server..
; mode=5: Download only missing files or files with size differences.
; mode=6: Same as mode 5, but also download newer files.

; This example will download all files, but only those files having filenames
; that match *.gif and *.eml

; Imagine our remote directory tree has these files and directories:

; 	accentedLatin1.txt
; 	accentedUtf8.txt
; 	alice.key
; 	anter_cert.pem
; 	chiliPepper.gif
; 	helloWorld.pdf
; 	abc/chiliPepper.gif
; 	abc/ghk/
; 	data/chiliPepper.gif
; 	data/xyz/dkimHtmlBody.txt
; 	data/xyz/dkimVerifyTest.eml
; 	data/xyz/emailForCreateDsn.eml
; 	text/frenchUtf8.txt
; 	text/helloWorld.txt
; 	text/PolishEmailBody.txt
; 	text/something/

; Indicate that we only want to create auto-create local directories (if needed)
; for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
; True, then the corresponding local directory is created for each remote directory
; traversed regardless of whether files within are downloaded.
$oFtp.SyncCreateAllLocalDirs = False

$oFtp.SyncMustMatch = "*.eml; *.gif"
Local $iMode = 0
$bSuccess = $oFtp.SyncLocalTree("c:/temp/subDir1",$iMode)

    ConsoleWrite($oFtp.LastErrorText & @CRLF)
    Exit
EndIf

; Show the files downloaded.

Local $i = 0
Local $sRemoteFilename
