Basic Tasks are simple one-action tasks that you define and run on-the-fly. The tasks have predefined profiles that cannot be modified. Use once and forget.
E.G. Open DocSpace, select Basic Tasks, choice Optimize> Compress, select file(s) and launch! All done.
Custom Tasks allow you to do multiple actions and custom-configure different profiles. These tasks are saved and you can re-access them when you need them.
E.G. Open DocSpace, select Custom Tasks, select your previously created task of interest (such a task that converts Word files to PDF and then compresses them) select your files,and launch!
Automation Tasks are the same as a Custom Tasks, except that you set up an automated Input Connector (i.e. Watch Folder). When files are dropped into the Input Connector, the task will automatically run, and deliver the output to a predefined output connector.
E.G. Outside of DocSpace, drop some files into a Hot folder, DocSpace will pick them up, complete the actions assigned to the task, then deliver the output to wherever you defined. Note that these Input & Output Folders may exist on your computer, or link to Google Drive, Sharepoint, Dropbox, and other cloud storage locations!
