File Island v0.3.1 — unsigned early access
File Island 0.3.1 — unsigned early access
File Island 0.3.1 is a focused interaction update for mixed-folder workflows and Split for Sharing controls. It keeps the v0.3.0 conversion and runtime boundary unchanged while making the two recording-critical paths easier to discover and operate.
What changed
- Mixed folders now show every non-empty image, video, audio, and unsupported group as an always-visible compact control with its file count.
- The active media group has a clear accent selection state.
- Switching groups opens that media type's own conversion parameters while preserving the independently configured image, video, and audio intents.
- Split-for-Sharing size and duration controls now use substantially longer slider tracks.
- Both sliders show five reference ticks and localized lower/upper range labels with units.
- General settings can optionally copy a successful one-input/one-output conversion to the macOS Clipboard for pasting into Finder or compatible apps.
- The success summary confirms when the output file was copied; batches and sharing splits never replace the Clipboard automatically.
- The compact Island remains 600 × 188 points in the action state.
Install
Download FileIsland-0.3.1-unsigned.dmg and its checksum, verify it with shasum -a 256, open the DMG, and drag File Island to Applications.
File Island 0.3.1 requires macOS 15 or later. The App contains universal arm64/x86_64 binaries, FFmpeg, ffprobe, the AVFoundation media validator, and its preset catalog. Users do not need Homebrew, Python, Node.js, or a separate media runtime.
This early-access build has an ad-hoc code signature, not an Apple Developer ID signature, and it has not been notarized. macOS may require System Settings → Privacy & Security → Open Anyway after the first launch attempt. Do not disable Gatekeeper.
Existing boundaries
- Fast sharing split accepts audited H.264 MP4/MOV with optional AAC audio and requires at least one positive size or duration limit.
- MP3 remains input-only; output is M4A, WAV, FLAC, or AIFF.
- WebP remains image input-only; verified image outputs are JPEG and PNG.
- Precise re-encoded splitting and named platform rules are not included.
Legal and privacy
File Island original code and assets remain All Rights Reserved and source-available. Bundled FFmpeg 8.1.2 remains under LGPL-2.1-or-later with the corresponding source archive, license, notices, and build record included with the Release. All conversion and splitting stay on the Mac.
