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/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/
