Bug description

I called add_videos on the command line without setting copy_videos.
Symlink creation failed, but instead of stopping, or copying the videos, the videos were cut and pasted (moved) per the printed output.

My concern is not the symlink failure (actually I meant to copy_videos anyway).

This behavior is dangerous - unexpectedly moving video files disrupts file organization designed to maintain experimental integrity.

Is there a way to catch the windows error regarding symlink failure, and copy the videos instead?

Operating System

Windows 10

DeepLabCut version

dlc version = 2.3.0

DeepLabCut mode

single animal

Device type

gpu

Steps To Reproduce

1. called dlc.add_new_videos(config, vids) on existing project (vids is a list of two videos)
2. got error below

Relevant log output

Attempting to create a symbolic link of the video ...
Symlink creation impossible (exFat architecture?): cutting/pasting the video instead.
C:\Users\original\path\to\project\videos\videoname.mov moved to C:\Users\projects\thisAnimal\dlcproject-DLC-2021-10-07\videos\videoname.mov
