For step 2, I recommend you choose "Move To Folder" because this option supports file recovery, if you find something wrong, you can click "Undo" button in the toolbar to put all deleted files back.

2. Why some file scan is relatively slow?
A:  If several huge size files have very little difference, in order to ensure the accuracy of the scan, the scanning speed of these huge files will be relatively slow, it is expected. if you don't want to scan certain type of files , you can skip them from preference to save some scan time. And you can also try to enable fast scan mode to speed up the file scan.
