Delete (Dupe-Safe)

Post by meteorquake »

There's a good interest in using Everything for handling duplicates.
Can I suggest there be a "Delete (Dupe-Safe)" command somewhere, perhaps under "Edit - Advanced", and an action command a shortcut can be assigned to.
Basically you want to remove duplicates, so you would do a dupe: search of all items in question which you wish to trim the duplicates from, which will typically be some part of a single drive, usually with a little bit of focus - you obviously don't want to be including backup drives and folders.
Here's where the "Delete (Dupe-Safe)" command comes in, because you would highlight the ones you want to delete, and delete using it. For each file it would go to delete, it will check there is a matching file in the dupe list of the same size (that is not the same file under a different alias!) AND do a full binary content check between the two files to verify they are actually the same, and only then do the delete, otherwise the delete will be skipped. On removal obviously the dupe list would be reduced (but the content check would always prove genuine existence). (For full implementation on content match failing you would check through the remaining possible dupes that could allow the delete to occur, although I think the number of such occurrances will be low and so probably no rush for that full analysis although it would probably be a trivial addition.)
This means you could actually just highlight the whole list and hit "Delete (Dupe-Safe)" and it would be trimmed to be unique items; but you may well want to sort the list and do "Delete (Dupe-Safe)" on a particular area to prioritise the dupe removals from particular folders.
I think it would save people a lot of anxiety and work in handling their duplicates.

I will consider a Delete (Dupe-Safe) option.

Thank you for the suggestion.



For now, searching for
dupe:size
should instantly give you a quick guide to possibly duplicated files.
dupe:size;sha256
will find duplicated content, but is much slower.
