FileZilla is the most commonly used program for uploading files to an FTP server. This tool is open source and completely free, so anyone can use it. It supports protocols such as FTP, FTP over TLS (FTPS) and SFTP. The latter encrypt all content sent to the server, ensuring that no one can intercept the files on their way to the server.
FileZilla lets you configure profiles to upload content to a specific address. You can add parameters such as an IP address, port, username and password. Thanks to this, all you have to do is select that profile and you will be able to manage the files on the FTP server, whether that's a local or external server.
With FileZilla, you can interrupt the download or upload of a file, and resume it later from the exact point you left it. However, the server you are downloading it from must support this function.
FileZilla is particularly useful for uploading a large number of files or large files, especially those larger than 4 GB, to a server. With this tool, you can take advantage of your connection's maximum speed, as well as set speed limits or IP filters.
If you are looking to upload files to an FTP, SFTP or FTPS server, then try downloading FileZilla.

It is reliable, free, and has a very practical site and connection manager. Otherwise, it provides the service you can expect from a complete FTP client, so it's hard to improve.

It's not the prettiest, nor the fastest, but if I had to count the times it has gotten me out of a jam, I would run out of time. It fulfills its purpose perfectly.
Filezilla Client 3.0 does not have the help file of its predecessor Filezilla version 2.2.32, which, although in English, was an appropriate reference source.
