Export your library to USB in Engine DJ.

Work through the blockers in order. Confirm the drive is exFAT or FAT32 and has room for the files plus roughly 500 MB for the Engine database, since a red capacity bar in Sync Manager means the selection is too big. Make sure the Job Monitor reads No jobs running before you start. A warning icon beside the drive means Engine DJ does not support it. And never rename a drive after adding tracks from it, because Engine DJ then stops detecting them. WAV masters fill a stick fast. Where the booth does not need lossless, the WAV to MP3 converter shrinks them without uploading anything.

Engine DJ recommends an exFAT partition for the best performance, and FAT32 is also supported. Check that your player handles both the file system and the size of the drive before you commit to it. Leave about 500 MB or more free for the Engine database, which is the part that lets a standalone player read your collection. Formatting wipes the drive, so move anything you care about off it first. More detail in prepare a USB drive for Engine DJ.

Usually the playlist was never actually selected, or the job did not finish. Reopen Sync Manager with the drive selected and check that the box is ticked rather than filled in, because a filled but unchecked Smartlist box means make no changes. Then wait for the Job Monitor to read No jobs running, and switch on the Packed column in the track list: a dot means the file is on a drive.

There is no export everything button, because Sync Manager works on Playlists and Smartlists. Either make one playlist that holds every track, or a Smartlist with rules broad enough to catch them all, then tick that single entry in Sync Manager. The other route is drag and drop: click the Drives icon in the Collection pane, select the drive, and drag tracks or folders onto its track list.

On the desktop side, yes. Open Preferences and under Library, Cloud Storage, set Dropbox to On. If Dropbox is not already installed on the same computer, Engine DJ prompts you to download it, install it and sign in. The cloud folder then appears next to your drives when you click the Drives icon, and you pack playlists to it the same way. Your hardware still has to support playing from it.

Yes. The Engine database written onto the drive carries playlists, cue points, hot cue points, loop points, beat grids, BPM, waveform data and filter and word search, which is why a player behaves like your desktop library. Anything you change during the set comes back the other way: plug the drive in and click Sync to Engine, and cues, loops, grids, BPM, key and star ratings update at home.

Engine DJ copies the audio files themselves, so the drive and the port it sits in do most of the work, not the software. A slow flash drive takes far longer than an SSD for the same playlists. Click the Job Monitor progress bar to see the running and queued jobs, and cancel one or all of them if you need the machine back before the export finishes.

No. Vibes handles the library side: it imports your Engine Library, tags tracks into vibes, analyzes BPM, key and energy, and exports finished playlists back to Engine DJ. Packing them onto a drive stays an Engine DJ job through Sync Manager. The same split applies elsewhere, for example in Rekordbox, Serato and Traktor.
