FTP Sync Download Tree w/ Must-Match Directory Constraints

See more FTP Examples

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

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

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

// 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.

// 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/

// Only enter remote directories named either "data" or matching "x*"
loo_Ftp.SyncMustMatchDir = "data; x*"
