Due to Android's scope storage policy, iBMSUnreal cannot read arbitrary BMS folders. So there's two ways you can import BMS files:

• Open zip file with iBMSUnreal: the app will unzip the file to its data folder.
• Connect the phone to your PC
  • If you want to import unzipped files, copy files into Android/data/com.YourCompany.iBMSUnreal/files/BMS (this method is super slow if you have a large number of files)
  • If you want to import zip files, copy files into Android/data/com.YourCompany.iBMSUnreal/files/imported

1. Open Files app
2. Put your BMS folder under iBMSUnreal/BMS

Simply run the game and select your BMS folder in the dialog.

Although iBMSUnreal is licensed under GPLv3.0, it includes non-free GPL-incompatible libraries like fmod. We are planning to address this issue by supporting free audio library as an alternative.
