Introduction
Home Library FTPClient is a Java library providing a simple interface to Home Library WebApp.
This library has following features:
- Current Directory: returns the pathname of the current working directory.
- Change Directory: to changes the current working directory.
- Change Directory Up: to changes the current working directory to the parent one.
- Create Directory: to create a directory in the root or in a subfolder.
- List Directory: to list the content of a directory.
- Upload file: to upload a file in a directory.
- Remove files and folders: to remove a file or a directory (including subdirectories).
- Test: a simple test to check the correct behavior of the features above.
The following sections will discuss each of these commands in turn, and discuss how to use them with Home Library FTPClient.
Configuration File
Home Library CLI is equipped with a simple configuration file to set the parameters and initial settings.
The fields are:
- URL_REPOSITORY: the URL of Home Library WebApp.
- USERNAME: username to connect to Home Library WebApp.
- PASSWORD: password to connect to Home Library WebApp.
- LOGIN: the portal login of the user who is using the library.
- ROOT_PATH : the ROOT of the VRE folder where the files and directory will be created.
The Configuration File cannot be modified by the final user, but it allows to use the CLI in different context.

Where:
- path: the path to the new working directory.
Example:
String mySubFolder = .. client.changeDirectory(mySubFolder);
Change directory up
To changes the current working directory to the parent one.
void changeDirectoryUp()
