No Ezxs Or Midi Libraries Were Found — In The Selected Folder

How to Fix “No EZXs or MIDI Libraries Were Found in the Selected Folder” – A Complete Guide

If you are a musician or producer using Toontrack products (such as EZdrummer, Superior Drummer, or EZkeys), you have likely encountered a frustrating roadblock: “No EZXs or MIDI libraries were found in the selected folder.”

This error typically appears when you are trying to install, relocate, or add an expansion pack (EZX, SDX, or EZkeys MIDI library) to your Toontrack software. Instead of loading your new drum sounds or MIDI grooves, the software rejects the folder you’ve chosen, leaving you stuck. no ezxs or midi libraries were found in the selected folder

In this detailed guide, we will break down: How to Fix “No EZXs or MIDI Libraries

Let’s dive in.

Step 4 – Reinstall the Expansion Pack

If the folder is correct but integrity fails: What causes this error

  1. Download the library fresh from your Toontrack account (My Products page).
  2. Do not extract the files to a custom location manually unless you know the proper structure. Instead, use the Toontrack Product Manager or the official installer whenever possible.
  3. Run the installer and choose your desired library location (internal or external drive).
  4. After installation, open your software and automatically scan, or manually add the folder again.

B. Confirm folder structure matches the host’s expectations

  1. Some hosts require the top-level folder to be the library (e.g., /Libraries/MyLibrary/...). Other hosts require you to point to a parent folder containing multiple libraries.
  2. If the library is inside an extra folder (for example, Downloads/MyLibrary/MyLibraryFiles), point the host to the inner “MyLibraryFiles” folder.

Part 1: Understanding the Error – Why Does It Happen?

Toontrack’s software (EZdrummer 2, EZdrummer 3, Superior Drummer 3, EZkeys) relies on a specific folder structure and metadata files to recognize expansions. When you point the software to a folder, it scans for specific file types and a database file. If these are missing or corrupted, you get the dreaded message: “No EZXs or MIDI libraries were found in the selected folder.”

On Windows (Command Prompt as Administrator):

mklink /J "C:\ProgramData\Toontrack\EZX\MyLibrary" "D:\Toontrack Libraries\MyLibrary"

Part 5: How to Prevent This Error in the Future

  1. Always use the Toontrack Product Manager for installations and updates. Manual copy-pasting of library folders often breaks the database references.
  2. Keep libraries on a stable drive – If using an external drive, use the same USB port and keep the drive letter consistent (Windows) or always mount to the same path (macOS).
  3. Do not rename library folders – Changing the folder name after installation can confuse the software.
  4. Backup your EZX.dat / MIDI.dat – This small file is crucial. If it goes missing, the library will never be recognized.
  5. Run regular integrity checks – Use the Verify Integrity feature every few months, especially after moving files.

2) Quick checklist (try these first)

  1. Confirm you installed the library files (not just a ZIP/installer stub).
  2. Ensure the folder you selected actually contains library files (sample folders, .mid files, or vendor-specific library packages).
  3. Check for nested folders — the app may require the library folder itself, not a parent or child folder.
  4. Verify file extensions aren’t hidden/changed (e.g., .zip left instead of extracted).
  5. Confirm you have proper read permissions for the folder.
