IMPORTANT! For all users who get a File Not Found error on first run. In any file manager do this:
1. Look for a folder called Android/obb/name.duzenko.
chessopeningexplorer on sdcard or external storage
2. There should be a 200+ MB file - it's a zip archive, so you can open with any app that supports zip.
3. Create a folder on a storage that has the most free space named "Chess Opening Explorer". (Note CapitaL letters - androis might be case-sensitive)
4. Extract files from zip (2) to the folder (3).
If it still does not work, try (3) and (4) on another storage.
