Yes, you have several options.
1. MediaMonkey has native duplicate finding ability built into the "Files to Edit" node,
which is located in the tree as a sub node of the "Library" node.
-The "Duplicate Titles" node will find and list tracks with the same title and artist.
-The "Duplicate content" node will analyze each file's audio content and compare
it to other file's audio content in your library. For duplicate content to work, you
must have the option ticked "Analyze tracks for duplicates (takes longer)" in the
Library settings. Then when you do a rescan of the files a hash will be generated
for each one, which is used for the check.
Both nodes will display all duplicates, so you'll have to delete the duplicates that
you don't want to keep manually. Though time-consuming, it is the safest way to
ensure that you don't delete tracks that you actually wanted to keep.
2. There are also scripts available to assist you in finding and deleting duplicates. Two popular options are:
-Advanced Duplicate find & fix by Bex ( http://www.mediamonkey.com/forum/viewtopic.php?t=13000 )
-Duplicate Report by Trixmoto ( http://www.mediamonkey.com/forum/viewtopic.php?t=16681 )
For more information regarding these scripts (including how they work and how to download,
install, and use them) you should consult the individual script thread (linked to above) as these
scripts are updated often and any description of them listed here would not be complete. In general
though, both scripts will make it easier to automate deleting a large number of duplicates.
