If you wish, you can put all your Web files in this one directory, and not have any subdirectories beneath it at all. If you don't have a lot of files, this is acceptable. If you have a lot of files, or if several people will upload files to different sections, you should set up more directory levels. An example of the next level of directory, such as a directory for news releases. A directory for individual staff pages.
Directory names can be upper, lower or mixed case.
Just remember that unlike Windows, Unix is case sensitive . Some people use upper case for directory names and lower case for file names, so it is easy to tell which are directories and which files. Other people mix them up. Think of this as up, over and down from where you started. This is opposite from most PCs.
