Renaming a file or folder
You can quickly rename a file or folder if you originally labeled a file or folder with the wrong name, or if the name needs to be updated. This is useful if a small number of files need to be changed, since you do not need to upload any files for the changes to take effect, but inefficient if you needed to rename your entire site.
To rename a file or folder:
Navigate to the file or folder.
Click on the Rename File link in the top-right corner of your window.
Enter the new name for the file or folder in the text field. You need to enter an extension if it is a file, such as .html for HTML files.
Click on the button. The file name has now been changed and the display updated to show the modified file.
