In Resources, to change a file's display name (i.e., the name that appears in your list of resource items):
Actions
menu, choose Edit
Details
.Update
.
Note: This will change the file's display name only, and will not affect the true filename (i.e., the filename at the end of the URL associated with the item, or the filename listed in the WebDAV connection to your site's Resources).
To change the true filename of an item in your site's Resources, download the item to your computer, save it under a new name, and then upload the renamed file to Resources.
Alternatively, if you have a WebDAV connection to your site's Resources, you can change the filename there.
