A FTP manager can be installed onto your computer which allows you to upload files from your computer onto your web server. The main advantage with a FTP manager is that you don’t have to login to cPanel all the time to upload your files. Instead you can download the software and upload files using it as long as you have an internet connection.
What is the best FTP manager?
I use FileZilla and it is great. It has lots of features and it is totally free but most importantly, it is very user friendly. It also works for most operating systems.
