Once you copied your files are synced you can ingest them to Flow. In Flow your files will be organised the same way as in Edge and your backup drive. That's why it's so important to chose a good destination path at the beginning of the whole process.
1. Select files
Start a new ingest job by clicking on the ingest icon.
After you selected the clips, you have to chose the Flow destination drive.
Click on 'start ingest', your files will be transferred to Flow.
