If you no longer need a note, you can delete it from the system. The way you delete a note is determined by the type of note it is.
For information about note types and classifications, see Working with Notes.
If the note you want to delete includes an attached external file, you do not need to delete the attached file. You just remove the connection between the application and the file by detaching it.
Some application-specific forms use the modal Notes form, instead of the standard Notes form. Deleting notes in these forms is different from deleting them in the standard dialog boxes. For details, see Notes Form (Modal).
NOTE: If you delete a reusable note in the Object Notes form, you only detach the note from the record; you do not delete the note. To actually delete a reusable note, you must be in the System/User Notes form - see below.
NOTE: If you delete a reusable note in the Object Notes form, you only detach the note from the records in the current collection; you do not delete the note. To actually delete a reusable note, you must be in the System/User Notes form - see below.
NOTE:If you attempt to delete a note that is attached to one or more records, when you try to close the System/User Notes form, the system displays an error and does not delete the note.
