If you are running a blog, the chances are at some point you will need to create an FTP (File Transfer Protocol) connection to your hosting provider. For example, this could occur if you try to upload a file of more than 500MB to your HostGator account. HostGator will not allow file sizes of more than 500MB to be uploaded via their CPanel file manager and they advise you to use FTP to upload files larger than this.
What you need to be made aware of is, if you use plain FTP to transfer your files, your data is being transmitted unencrypted which can be intercepted and read, this includes your passwords! So for security reasons it’s not really a good idea to use plain FTP.
