Does Sleeve Copy or Import Your Music? | Sleeve
Frequently asked questions
- Does Sleeve copy or import my music into the app?
- No. Nothing is moved, copied, or duplicated, so connecting a source costs you no storage and your files never drift from the originals.
- What happens if I rename an album at the source?
- Sleeve follows. Rename it at the source and the rename appears in Sleeve.
- Does Sleeve ever rename or reorganise my files?
- No. It never renames or reorganizes anything itself.
- Does it read FLAC from a NAS?
- Yes. A network share at home over WebDAV — Nextcloud, Synology, QNAP and most NAS boxes — is one of the four source kinds.
The short answer
The music you actually own is already somewhere — a folder on your phone, a drive in the cloud, a NAS humming in the next room. Sleeve reads it where it is and hands it back as one library.
There is no "import" in Sleeve.
Nothing is moved
Nothing is moved, nothing is copied, and no second copy is kept. Two consequences follow, and they are the reason this design exists:
- Connecting a source costs you no storage. A 200 GB library costs 0 GB.
- Your files never drift from the originals. There is no second copy to fall out of sync.
Renames propagate
Rename an album at the source and Sleeve follows. It never renames or reorganizes anything itself — which means the library you see is always the library on disk, not a copy that remembers what things used to be called.
Four kinds of source
- A folder on this device — anything in Files, including a USB stick or SD card
- A cloud drive — iCloud Drive, Dropbox, Google Drive, OneDrive, all through Files
- A network share at home over WebDAV — Nextcloud, Synology, QNAP and most NAS boxes
- Straight from your computer over the same Wi-Fi, with a browser and no cable
Lossless and honest about it: FLAC, ALAC, AAC, MP3, WAV and AIFF, played as they are — nothing is re-encoded. Gapless across an album, so a live record stays one performance. ReplayGain, so tracks from different sources sit at the same loudness. Format, bit depth and sample rate stay on screen — a 24/96 FLAC says 24/96.
