There is only one file type that uses the .LOGIC extension:
Logic Pro Project File
Audio project created by Logic Pro digital audio workstation (DAW) software; stores multiple audio tracks on a timeline and can include recorded sounds, imported audio data, and loops; may also include transitions, effects, and other audio edits; doesn't contain the actual audio data, but rather stores references to audio files.
Logic Pro is used by musicians for producing music. Logic Pro supports the recording, editing, and mixing stages of audio production.
