Notes about the FES file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The FES file type is primarily associated with 'Topicscape' by 3D-Scape Limited. Topicscape is a memory aid, a thinking tool and a "let's get organized" assistant that works on your computer screen in 3D. This file will contain the metadata from the Details Panel from that occurrence. Do not rename to remove the 'fileless-' or edit the content if you are likely to re-import the file to Topicscape.
