You can also use the File Manager within your account to edit files on your website. Perform the following steps to edit a file on your website using the File Manager.

1. Login and click the "Account" button towards the top left of the page.
2. Go to Manage->Files
3. Right click on the file you would like to edit and go to "Edit". If you are trying to edit an image file, click the "Switch To Image Manager" button and edit the image there.
4. Save your changes.

Once uploaded, you should be able to access your file at http://www.yourwebsite.com/filename.

If you do not want to use the File Manager to edit your website files, you can use an FTP/SFTP program such as FileZilla, WinSCP, or any other compatible FTP/SFTP program to edit files on your website.
