Then tap the “…” button in the app, select “Batch import” to import files.
The files in “import” folder will be deleted after they are imported successfully.
The files that can not be imported will be left in “import” folder. You can drag “import” folder back to your PC to check. The files that still in the folder are the files that can not be imported.
