In order to use your Word Press website you are going to have to have access to your server
via FTP in order up upload files, plugins, change your themes, change file permissions in order to edit PHP files just to name a few of the more common uses. I find that uploading video files is much faster using FTP.
My browser is Fire Fox so I use the add on Fire Ftp. If you use Explorer do a search for alternative FTP software, they really are very similar.
So what is FTP (File Transfer Protocol) it is a software program that allows you to connect to the files that reside on your server, allowing you to upload new files, delete old ones, manage permissions to name a few. The image below is the FireFTP by Mozilla, I will use this one for the tutorial but there are numerous free downloads of FTP software. Down Load Fire FTP
If you are currently using Fire Fox as you browser.
Download and install FireFTP program to your computer.
To connect to your site look for the drop down menu in the upper left hand corner of the Fire FTP panel and click the small gray triangle, select create an account
to access the Account Manager. Click the Main tab and enter your information. In most cases this is the only place you are going to have to put any information. The (Connection) and (Advanced) tabs are pre-set for the common FTP settings so for now don’t worry about making any changes in these tabs.
After you have inserted your information click OK to close and save your account information.
Navigate to the upper left hand corner again and now you should see your Account Name in the drop down menu. Next to your account name you will see the tab (Connect) or (Disconnect) click connect and if your settings are correct you will connect to your server.
The FTP directory window will appear, the left hand side is your computer’s directory tree and the one on the right is the server’s directory tree. You navigate through the server files the same way you would use the directory tree on your computer. You will need to get familiar with the file structure on your server, the area that you will do most of your work in will be in the/public_html/ wp-content directory. Locate that directory and find the file folders, plugins, themes and uploads. These are the most commonly used folders.
CAUTION unlike your computers file manager if you double click a file it will transfer that file in the direction the little green arrows located in the bar that divides the two windows. Don’t worry you can always delete any file that you may move accidentally and trust me you will do it at least once.
Double clicking the file folders will open them, once the the directory is open you must use the green arrows to send the files in your direction of choice. For example looking at the directory above the highlighted file on the top left would move to the Content directory (/public_html/wp-content) on the server if you were to click the right pointing green arrow.
Open the folder you would like to transfer the file to before you click the green arrow.
You can manage your files by right clicking the file and choosing the option of your choice, delete, make a new directory etc.
Go ahead and give it a try.
