The VideoLAN Forums

The problem is as follows: when you chose the option "Group videos" in video section and then chose group by name, you'll not be able to delete multiple folders all together and not even just one folder, instead, you'll have to go to the folder you want to delete, and then select all the files and then chose delete. This might be a no problem to most people, but in my case it is, and the reason is because I have ton of folders (videos), so selecting one folder at a time is time consuming, that's why I hoped you could add the option to delete in group mode.
Best regards from a sincere VLC user.

Are you talking about ungrouping the videos or delete the files?
If you are talking about ungrouping, you can open a group and then, you have an "Ungroup" option in the top bar.
