Nothing it won’t delete or greys out the delete item in menu not sure which as away from home at the moment. I looked in the manual but no guidance in there!
When you press OK on a recording in the media list, one of the options is lock/release. This is a toggle, if the recording is locked selecting it asks for the password (default is 0000). Once unlocked delete should be available.
You can’t initiate a 2nd delete while a previous one is being deleted (On Linux this takes a while). You can though build a delete queue using File Managers edit mode.
