The plugin supports key FTP operations such as:
- File and Directory Creation: It can create new files or directories on the FTP server, facilitating dynamic deployment or setup of remote resources required by the application.
- Existence Verification: Functions are available to verify if a given file or directory exists remotely, enabling conditional logic in the installer based on the server state.
- Renaming: Both files and directories can be renamed remotely, supporting workflows that require organizing or versioning resources on the FTP server.
- Deletion: It supports safe removal of files and directories on the server, ensuring the installer can clean up or update remote assets as needed.
Under the hood, the plugin likely encapsulates standard FTP commands (such as MKD, RMD, RNFR, RNTO, DELE, STOR, and NLST) within its exported functions, handling the complexities of connection establishment, authentication, command sequencing, and error management.
The plugin interfaces with NSIS via exported functions callable directly from NSIS script, using string parameters formatted as FTP URLs containing authentication credentials and resource paths. This approach simplifies usage in script form, allowing developers to embed FTP control logic without resorting to external scripts or separate executables.
By leveraging this plugin, NSIS installers can automate remote file system manipulations on FTP servers during installation, enabling robust and flexible deployment scenarios, such as downloading updates, managing remote configurations, or maintaining server-side application components — all transparently integrated into the installation workflow.
