As you might understand from the title, AndFTP is basically an application which makes possbile to work with files through FTP, FTPS, SCP, SFTP protocols, directly from your phone. Inside the intuitive interface you can start by configuring the connection for your remote FTP server. During this process, you are required to provide important information, like hostname/IP address, type of protocol used, port, username and password if it's the case, and a couple of additional options.
If everything is correct, you can start using this application to work with folders and files stored remotely. You can perform common actions such as upload, download, rename, delete, changing permissions, run custom commands, open, and so on. It even comes with a synchronization feature which works mostly the same as the ones found inside apps made by cloud services. In terms of security, you will be happy to know that AndFTP brings support for SSH RSA/DSA keys to make thing a lot more safe while transferring files and folders over the Internet.
