Bulk delete uploaded files?

[sxdjt]

Hi - I just accidentally uploaded a folder with ~200 models in it that I didn't mean to put in to Manyfold. Is there a way to delete them en masse?

Under Site Settings > Advanced Tools > Advanced Administration > Files I can select files individually, but...

1. "Batch actions" is greyed out and does nothing
2. What I assume to be the "select all" box does nothing

What I would like: I would like to be able to filter the file list (which works as expected), tick the "select all" box and then from Batch Actions, delete all selected files.

I'm planning bulk file deletion soon, but at the moment the only way would be to delete the model itself, which will delete all the files inside it.
