deleting a special part of a filename

I want to delete the brackets within a filename and the content between the brackets.
e.g. IPtable_20240816_subnet(floor#1_room#2_254).txt

In this case i want to delete this part "(floor#1_room#2_254)".
How can i realise it?

Many Thanks

Found a solution:
Its the replace methode:

Replace: " *\(.*\)" (without quotation marks"
With: leave blank
Use regular expressions.

Thanks to all

As an alternative approach, the Replace method can be employed as follows:

Replace: (*)
With: leave blank
No regular expressions are required.
