Hi, I admit that there are lots of duplicate file finder software, even paid or free. But their issue is, they are slow, it takes countless hours for them to find anything and compare. Since "Everything" is incredibly fast, this could be added as an additional feature or could be created as a different application based on everything's search engine, as a result it could be the fastest duplicate file finder on the market.

Everything has some dupe functionality that may help to find potential duplicates.
I say potential here because Everything does not index file contents only file names and therefore does not compare the actual file contents.

Please try searching for dupe: to find files with the same filename.
This will give a quick indication if you have a duplicated file.

In the Everything 1.4 beta you can also try dupesize: or dupedm:

dupe:, dupesize: and dupedm: work best if you specify a file type, eg: *.mp4 dupesize:

dupedm:

Eh?

Documented somewhere?
What might be a scenario where a dupedm: might come into play?
I suppose the full date/time are taken into consideration, so even to the same precision as different Windows OS return?

Also note that you need to enable the respective (fast) sorts in Everything | Options | Indexes.
Fast size & Fast date modified (if you want that).

It's not officially documented anywhere, it does exist in the Search -> Advanced Search menu. It's also mentioned under the search syntax (719b+).

dupedm: -find files and folders with the same date modified.
Useful for finding a duplicated file that was copied on the local file system since copying a file does not change the date modified.

The dates must match exactly to be considered a duplicate.
FILETIMEs are used for dates.

Also note that you need to enable the respective (fast) sorts in Everything | Options | Indexes.
Fast size & Fast date modified (if you want that).

These options will be enabled by default in Everything 1.4.1.
