Quedo puts on your web server a password-protected area where people can upload files and annotate them online. Each user can manage his own separate folder, or you can have many people share the same directory. The administrator can choose to limit the permissions for certain users. People can: upload, rename, delete files / folders,- create/extract ZIP archives,- send files by email,- chmod (recursive chmod for folders). Cut, Copy and Paste files and folders to a web-based Clipboard. Delete objects to a Trash bin (and restore them). You can add descriptions to files and folders (to make notes for yourself or to leave messages to other people). The administrator has access to logs that record and timestamp each operation, for each user. Logs also contain information about failed operations. DHTML interface loads quickly. Context menus and dialog boxes appear on screen without refreshing the page. It has four different views, with icons and thumbnails for picture files.
