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 nSuccess
LOCAL oFtp
LOCAL nMode
LOCAL oSt
LOCAL nNumFiles

LOCAL cRemoteFilename

nSuccess := 0

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

oFtp := CreateObject("Chilkat.Ftp2")

oFtp:Hostname := "ftp.something.com"
oFtp:Username := "my_login"
oFtp:Password := "my_password"

//  Connect and login to the FTP server.
nSuccess := oFtp:Connect()
IF (nSuccess != 1)
    ? oFtp:LastErrorText
    oFtp:destroy()
    RETURN
ENDIF

//  Set the current remote directory to the root of
//  the tree to be downloaded.
nSuccess := oFtp:ChangeRemoteDir("/subDir1")

    oFtp:destroy()

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
//  1, then the corresponding local directory is created for each remote directory
//  traversed regardless of whether files within are downloaded.
oFtp:SyncCreateAllLocalDirs := 0

oFtp:SyncMustMatch := "*.eml; *.gif"
nMode := 0
nSuccess := oFtp:SyncLocalTree("c:/temp/subDir1", nMode)
