Settings and File Types
One DJ saves its setting files in a couple of different locations.
The metadata of audio files is saved to the same directory as the file and named filename.onedb. These files contain the beat grid, waveform data and cue points of the clip and can be copied to other computers with One DJ to avoid reanalyzing.
Other settings - concerning layouts, controller settings and databases - are saved in following locations:
OS X: [user]/Library/Application Support/AudioArtery/TheOne/
