FTP Sync Upload Tree w/ Must-Match Filename Constraints

See more FTP Examples

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

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

    // Possible synchronization modes are:
    // mode=0: Upload all files
    // mode=1: Upload all files that do not exist on the FTP server.
    // mode=2: Upload newer or non-existant files.
    // mode=3: Upload only newer files. If a file does not already exist on the FTP server, it is not uploaded.
    // mode=4: transfer missing files or files with size differences.
    // mode=5: same as mode 4, but also newer files. 

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

    // Imagine our local 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/
