' 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.
