See more SFTP Examples

Demonstrates how SFTP 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.

    // 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.

    // Only enter remote directories named either "data" or matching "x*"
    Set ComSyncMustMatchDir Of hoSftp To "data; x*"
