how do I delete an audio recording in quicktime 10
Close the QT X player without saving the recording. If you have already saved the recording, then locate the saved file and trash it in the normal manner. If you are referring to a temporary or saved file entry that shows up in the "Open Recent" list, the system will automatically reclaim the space as part of the routine system clean up if/when the file is no longer available. If you simply wish to immediately remove it from your "Open Recent" list before the system removes it, then use the "Clear Menu" option to manually clear the "Open Recent" list.
