Denon DJ Engine Prime - Library Optimization

When organizing your library or creating different databases for different events, you will want to make sure that all the extra baggage is removed. In this article, we will discuss how to optimize your hard drives and Engine Prime library. 


Library Optimization

When tracks are imported into your Engine Library and analyzed, information for those tracks is stored with the Engine Database file. This includes track data like the album artwork, waveform, cue and loop data, etc. 

However, when a track is removed from the library, it's database entry is not immediately removed. You may notice that simply removing tracks from your library does not automatically result in a more efficient database. 

This is where the Library Optimization tool comes in. 

In the Engine Prime Settings > Library > System you'll find a button for Library Optimization. Running this cleanup utility will remove all excess data from tracks that are no longer stored in the library, reducing your database size and improving the performance of your library. 


Why does database optimization matter?

The most important reason to keep your database clean is to prioritize performance when using a shared drive between multiple SC5000 Prime players. To do this, the combined database size in the Engine Library folder should be no larger than 2.4 GB (around 10,000 songs). 

If you are having trouble with multiple players loading songs from a networked drive, your database may be too large. 


When should I run the Library Optimization?

Library Optimization should be run after removing tracks from your collection to reduce the size of the database. 


When is it unnecessary to run Library Optimization?

  • If tracks have not been analyzed or there is no artwork, you will not see a reduction in database size. 
  • If you have not removed any tracks from the collection. 


Does the Library Optimization work for the database on my external drive?

Yes, if tracks are removed from crates on your external USB drive or SD card, running the Library Optimization will refresh the database on the connected drive.
