Downloading a complete directory via FTP in Java is not a native single-command operation. Unlike downloading a single file, you must programmatically traverse the remote directory structure and recreate it on your local system. The industry standard for this task is the library. Essential Setup
While Apache Commons is the most popular, other libraries offer similar or simplified functionality: A lightweight alternative known for ease of use.
To get started, you must include the commons-net dependency in your project. You can download the JAR directly from the Apache Commons Net website or add the following to your Maven pom.xml :
Always set ftpClient.setFileType(FTP.BINARY_FILE_TYPE) to prevent data corruption in non-text files like images or ZIPs.
Primarily used for SFTP (Secure FTP over SSH), which is often preferred for security. Download entire FTP directory in Java (Apache Net Commons)
Because the FTP protocol does not have a native "recursive download" command (like mget in some CLI clients, which just iterates files), you must implement a recursive function. This function should: in the current remote directory. Create local directories if the remote item is a directory. Download files using a stream if the remote item is a file. Implementation Example
