Describe the bug

Hi!
When trying to delete multiple large folders - tens of GB in size - I get the error "An error occurred" when this option is selected: ExplorerPatcher > Properties > File Explorer > Always use legacy file transfer dialog.

Everything works well, how it was designed when "Always use legacy file transfer dialog" is disabled.
Tested on Windows 10.

Expected outcome

Show the regular delete message.

Actual outcome

Please check if you enabled the option register as shell extension, disable it by opening up the EP properties application, go to File Explorer, and untick Register as shell extension.

Hello! I didn't enable File Explorer > "Register as shell extension" because of the warning in the documentation and I don't really need the legacy file tranfer dialog. Best wishes!
