A. 1. Use the app's interface: Check if there is a multi-select option in the app. Tap and hold on a file to see if it allows selection of multiple files. 2. Organize files: Create folders within the app to group files, making it easier to manage them individually.
B. 3. Use the Files app: If multi-selection is crucial, consider using the Files app on your iPhone, which allows for easier file management.
