Chilkat2-Python

Filter Files and Directories in an FTP Sync

Demonstrates the synchronization filter properties SyncMustMatch, SyncMustNotMatch, SyncMustMatchDir, SyncMustNotMatchDir, and SyncCreateAllLocalDirs.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: A real sync rarely wants every file. These semicolon-separated wildcard filters shape the set: the MustMatch pairs include only matching files/directories, while the MustNotMatch pairs exclude them — letting you, say, publish only web assets while skipping build artifacts and caches. Directory filters also prune traversal, avoiding wasted time descending into folders you do not need. They apply to the tree-sync methods such as SyncLocalTree and SyncRemoteTree.
