## Describe the issue
 

I have tried to rip the Les Miserable (Original French Concept Album which has 2 discs. Roon finds only the second disc. In the Rip folder both discs are available. Please advise how I get the content of both discs made available in Roon My Library. Your help is much appreciated

Hi @user255,

Thanks for taking the time to write in! Sorry to hear about your issue with getting Roon to properly indentify your content.

Before anything else, I think reivewing this KB article on multi-disc sets will be helpful to you:

> **[FAQ: How can I ensure multi disc sets and box sets are identified properly?](https://help.roonlabs.com/portal/en/kb/articles/faq-how-can-i-ensure-multi-disc-sets-and-box-sets-are-identified-properly#Identifying_Multi-Disc_Sets)**

> If you’re importing a multi-disc set, the best way to ensure it’s identified properly is to make sure the track listing matches the original release. Identifying Multi-Disc Sets For best results, make sure the whole set is in its own folder, and make...

Roon uses folder structure and file tags to determine disc numbers. If the two discs are in separate folders without proper naming or tags, Roon might think they are separate albums or skip one disc.

If the first disc’s files don’t have proper DISCNUMBER tags or are missing track numbers, Roon can’t match them.

Before anything else, make a fresh backup of your current Roon database for safekeeping.

Then, try the below and let me know if it helps:

- Go to your storage folder for the album.
- Create a main folder like: 
  - Les Miserables (Original French Concept Album)

- Inside that folder, create two subfolders:
  - CD1
  - CD2

- Move the respective tracks into the correct subfolder.
- Make sure the track filenames start with numbers like:
  - 01 - Track Name.flac
  - 02 - Track Name.flac

- In Roon, force a rescan of the album folder: Settings → Storage → [Your Folder] → Force Rescan

From there, Roon will group both discs under one album as:

```
Les Miserables (Original French Concept Album)
Disc 1
Disc 2
```

You can also verify under Album → Edit → Merge Discs if it doesn’t automatically combine them.

Let me know if the above helps!👍

It looks as though you have a CD-ROM drive attached to a Nucleus, and as you have found, the CD ripping function of Roon OS does not handle box sets at all well. You will have to massage the file and folders manually as suggested by @benjamin.

This limitation of the ripping function is why many of us prefer to use a third-party app such as dBpoweramp for ripping our CDs and boxsets.
