On Android, Cubasis stores its files in an app-specific directory which is only accessible by Cubasis and certain file manager apps from the Play Store. It cannot be accessed by the Android Files app.
This new storage location was introduced with Cubasis 3.3.2 to comply with Google’s mandatory new storage requirements. When updating from an earlier Cubasis version to Cubasis 3.3.2 or later, a dialog guides you through the process of copying the MediaBay data from the old to the new storage location, i.e. from the legacy Cubasis 3 folder to the new app-specific directory.
After this process is completed successfully and you see all your files in the MediaBay, we recommend that you delete the old Cubasis 3 folder using a file manager app, unless you want to keep it as a backup. The legacy Cubasis 3 folder is no longer accessed by Cubasis 3, which means that placing a file inside it will no longer make it appear in the MediaBay. Instead, use the Import button to copy files from an external location into the MediaBay. To delete the Cubasis 3 folder using the Android Files app, scroll down to “Internal storage”, tap the dots next to Cubasis 3, then tap Delete. The exact wording and layout may vary depending on the device manufacturer. The following sequence of screenshots illustrates the process in the Files app on an Android 11 Google device:
If the process of copying your Cubasis data to the new location fails, insufficient free disk space is the most probable cause. Cubasis requires as much additional disk space as the legacy Cubasis 3 folder takes up (at least until copying succeeds and you delete it manually). To free additional disk space, open the Android Settings app and go to Storage. The exact wording and layout of this Settings page may vary depending on the device manufacturer. The Manage storage button offers several options to clean up and make more space. Tapping Other apps shows you a list of apps and the amount of storage they require, helping you to decide if there are any memory hungry apps that you no longer need. Likewise, the other categories allow you to view and delete files that take up a considerable amount of disk space. Once you’re done, launch Cubasis 3 again to restart the process of copying from the old to the new storage location.
Should the process of copying your Cubasis data fail multiple times, an additional option appears which is called: Abort - I am aware of the consequences and will import the existing data through the MediaBay. If you enable it, Cubasis will no longer show the Cubasis Data Location Change dialog at launch, which means that you can continue to work with Cubasis, but your MediaBay might be empty. There are two ways to manually copy your old Cubasis 3 data into the MediaBay now. Either use the Import button in the MediaBay to import individual files, or use a file manager app to copy the /Android/Cubasis 3 directory to the new location /Android/data/com.steinberg.cubasis3/files/Cubasis 3.
