I just have some new thoughts about the handling of file deletion and\nundeletion in the 2010s. The key points are:\n\n(1) ALMOST NEVER DELETE DATA PHYSICALLY. Today's new computers usually\ncome with 500GB+ disk space, so deleting files to save space is less\nand less a necessity. So a new Recycle Bin concept could always\npreserve deleted files physically until there is really a space\nshortage or the user intends to permanently eliminate private\ninformation immediately.\n\n(2) FOCUS ON THE REASON, INSTEAD OF THE DATA. Sometimes we have a\nreason to delete a file or folder, but later we have a new reason to\nrecover it, and later we may have a new reason to delete it again...\nWe humans are not used to reviewing all possible reasons for deletion\nand undeletion all at once. So I think the role of the Recycle Bin\nshould be a journal for the user to record his reasons, from time to\ntime, for a file/folder's "deletion" and "undeletion". For example, a\nuser may like a game, movie, song or other type of content at one time\nbut wants to delete it at another time but later wants to recover it.\nIt's really all about his reasons to hate or like the same content\nover time. It's really about the user's scoring and commenting about a\nfile in the file system, rather than the file's physical necessity to\nexist or not. If the user gives a file a very low score and a comment\nabout why it's so undesirable, the file can be hidden in the Recycle\nBin. If the user later has a mood to recover it, the user will be\nshown his previous comments about this file and determine if he really\nhave new, good reasons to undo his previous decision.
