Hi,
Does Mc can group the same songs name without to have other not "doublons" to be appear?
Thx (i hope i am clear if not feel free to ask more)

[MrC]

Are you asking if you can find duplicate track names without showing non-duplicates?  In other words, Duplicates Only?

[kurushi]

yes exactly again MrC you save me ^^
ps:title of the topic renamed

[MrC]

The easiest way is to use a Smartlist using the Modifer: Only Duplicates of and select the fields you want compared; in your case it's Name.  Add more fields as necessary to narrow the possible mismatches (for example, a track named "Angel" is listed 10 times in my library, by 9 different Artists).

Add also a Modifier: Sort by and select Name to automatically sort the list.

Thx MrC for the answer it's for a french user in the french section of the forum but i 'll use it too.
Thx again MC and MrC rocks !

[MrC]

Nice words - I smiled.

There are other options  for owners of large libraries who are interesting in de-dupe-ping...

I have a routine that's extensive but works for me . 

Cannot de-dupe using metadata/tags...must use an analysis of the audio content...

[jack wallstreet]

I'm just plain lazier than Mr. C.   I use the search wizard which already has the "only duplicates of" and a nice drop down check box list.  I am disgustingly lazy about that.  I try to convince myself to use the smartlist and can't get myself to do it.

[MrC]

A Smartlist is just a remembered Search query.

[kurushi]

Works like a charm i use smartlist so i don't need to make 2 times the same thing
Thx to all who have helped!

I have a large library and am looking to remove duplicates.
Have use the Possible Dups Smartlist, but it only does so much.
Would like to use only a part of a field (say the first 8 characters of ALBUM) so it would find dups of Anthology 1 disk1 and Anthology 1 DK1)
With this I would use the [artist],[name],[Part of Album],[track #]
Another way would be to use part of each field (say first 8 characters of [artist] and first 8 characters of [name], and first 8 characters of [album]
this would increase my dup findings as the first of each field is usually correct and the end is not.

I don't think you can do this kind of comparing in MC. But you could use more general criteria to create a large smartlist based on some kind of duping and then sort and prune it.

To go back to an older suggestion, this part of the program would be greatly improved if the wizards that make MC took a good look at Calibre - it's based on Python and has some excellent functions to de-dupe its library, including the necessary ability to mark specific pairs as not dupes.

[MrC]

Another way to do this is to define a custom calculated user-field, that defines the criteria you want, for example, a field named _Dup_Helper defined as the first 8 chars of both album and artist:

  left([album],8)_left([artist],8)

and then you can use the search query modifier:

   ~dup=[_Dup_Helper]

and even more:

   ~dup=[_Dup_Helper],[Name]

[TXgary]

yes, this would work, but my database is so large that it would take "days" to populate the dup field.

[MrC]

yes, this would work, but my database is so large that it would take "days" to populate the dup field.

I don't think I understand. You were going to write the rule in a smartlist.  Instead, you'd write it in a user field.    Why would it take days?

[TXgary]

I will try and see what happens. 
Thank you

[TXgary]

Yes, great solution, but with a large database it does take hours to populate the records.

[nickeaston]

In my opinion, based on several years of de-duping of a third of a million tunes, comparing tags may be all the typical user needs, but there are more accurate methods of finding and deleting duplicates based on audio content fingerprinting, using tools like YADB, DoubleKiller, and SongKong, a relatively new app which interfaces with MusicBrainz and Discogs databases.

I have a duplicate problem. I have a large library and MC18 loads my Itunes Library as well,causing duplicates. I use my MC as default and then after I am done impotring I send what I want on my ipods to Itunes and MC reloads them . I have 8,000 duplicates because of this. I move iTunes library out on My MUSIC and told MC to ONLY IMPORT FROM MY MUSIC. I also told MC to IGNORE iTINES LIBRARY. How do I get the 4000 dups removed easily without one by one deleting. I also have to delete an iTunes duplicate TWICE for it to actually delete. ANY HELP WOULD KEEP MY SANITY.
