There may be times you need to add files to your website, but can’t upload them to your WordPress Media Library. Depending on where your website is hosted, this restriction could be anywhere from 2 megabytes and up. To check what the restriction is on your site, you can login to your WordPress Admin panel and from the left hand menu choose under MEDIA/Add New. For example, mine says: Maximum upload file size: 64 MB.
However, you can upload, using what is generally referred to, by FTP. This means File Transfer Protocol and it’s built into your Windows operating system.
In Windows, you don’t need any special software. FTP sessions can be established using an MS-DOS prompt. You can see in this picture, how it would look to upload a file using DOS. In this picture you will see that after I logged into my server, I’ve used the CWD command to navigate to the directory I want to put the file, told my computer to upload it using PUT, and then set the permissions on it using “quot site chmod 0755 perldiver.cgi.”
But fortunately, there is an easier way. There are programs you can install called FTP clients which will run in a Windows program on your computer to make this job a lot easier for you. One such program is called CORE FTP. There is a free version and a version you pay for, but I’ve always found the free version could do everything I wanted it to do. You can find the software here: http://www.coreftp.com/download.html
Below you will find some video tutorials that give you instructions on how to set it up and use it.
Of course, you will need your FTP username and password for your website, to enable the program to work. If you don’t have this information and I setup the website for you, please contact me, and I will get it for you.
