Lightweight File Downloader for Mac & PC
Overview
A lightweight file downloader for Mac and PC is a small, low-resource application focused on fast, reliable downloads without the bloat of full download managers. It emphasizes simplicity, speed, and a clean interface while offering essential features for everyday use.
Key features
- Minimal footprint: Small installer and low CPU/RAM usage.
- Pause/Resume: Suspend and resume downloads, including after network interruptions.
- Parallel connections: Use multiple connections per file to increase download speed.
- Batch downloads: Queue multiple files and manage them in a compact list.
- Browser integration: Simple browser extensions or protocol handlers to capture download links.
- Checksum verification: Optional MD5/SHA1 verification to ensure file integrity.
- Cross-platform UI: Native look-and-feel on macOS and Windows; small differences to match platform conventions.
- Lightweight scheduler: Basic scheduling to start downloads at a chosen time (e.g., off-peak hours).
- Low-disk footprint storage options: Choose temporary folder or final location; auto-clean temporary files.
- Basic proxy support: Manual proxy configuration (HTTP/SOCKS) for advanced network setups.
- Notifications: Minimal system notifications when downloads complete or fail.
Typical user flows
- Add URL (paste or use browser capture) → choose destination → start download.
- Queue several URLs → reorder or pause individual items → resume when ready.
- Schedule large downloads overnight → verify checksum after completion.
Technical considerations
- Use asynchronous I/O for non-blocking downloads.
- Implement segmented downloading (range requests) when server supports it.
- Respect Content-Disposition and MIME types for proper filenames and handling.
- Provide safe defaults: sensible timeout, retry limits, and disk-space checks.
- Clear logging for failed downloads and HTTP status handling.
