Deleting a twrp backup

[dad2noah]

Anyone know how I can delete a backup I made using the twrp app?
I try deleting it from the *my files* app in the phone, it won't work.
I don't see an option to delete the backup in the twrp app itself.
And trying to delete it via the computer brings me to a *write protected*error.

You should be able to delete it from within TWRP. When you select a backup file there is an option to delete it.
