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:
