The djay Media Library database is used by djay to store playlists, history, the queue, as well as all per-song metadata like cue points and loop regions. It is kept in the "User Data" folder inside the "djay" folder that can be accessed in the "On My iPad/iPhone" section in the "Files" app
In very rare cases this database can get corrupted, or there can be a version mismatch when switching between different versions of djay (older versions of djay might not be able to read databases modified by newer versions).
When this happens, djay will show you an alert like these:
You have the following options:
- Select Continue to create a new empty database. The corrupted or incompatible database will be saved.
- Select Learn More to get to this support article. You can then restore an older version of the database from backups (see below).
To help us improve the stability of djay, we would appreciate if you could also contact our support team with information about the problem and attach a copy of your corrupt database.
djay automatically keeps backups of the djay Media Library:
- Every time you launch djay, a backup is created unless one was already created on that day.
- Up to 10 backups are kept. Older backups are automatically deleted.
These backups are stored in the folder "Backups" in the same "User Data" folder containing "djay Media Library". Each backup is kept in a folder named with the date when the backup was created (e.g. named "2023-03-18" for March 18, 2023).
In order to restore a backup, replace "djay Media Library" in your "User Data" folder with another version from your backups:
- Launch the "Files" app on your iPad or iPhone.
- Select the "Browse" tab.
- Select "On My iPad/iPhone" under "Locations".
- Select the "djay" folder and navigate into the "User Data" folder.
- Long-press (tap and hold) "djay Media Library" and select "Rename" to rename the existing database. We suggest adding a suffix like the current date to the name.
- Navigate into the "Backups" folder and then into the folder representing the most recent date.
- Long-press (tap and hold) "djay Media Library" and select "Copy".
- Navigate back to the "User Data" folder.
- Long-press the screen and select "Paste" to insert the backup database.
Afterwards you can launch djay to use the restored djay Media Library.
