Snowsky Transfer

Snowsky Transfer is a Linux desktop application built with Tauri 2 for transferring music to the Snowsky Echo Mini over USB/MTP or mounted USB storage.

The app copies supported audio files as-is. It does not transcode files or improve audio quality.

Version: 0.1.2 beta

Features

• Connect directly to a device through libmtp without an additional daemon
• Support for mounted USB storage devices
• Add files through a file picker or drag and drop
• Transfer supported Echo Mini formats: MP3, FLAC, OGG, WAV, and M4A
• Saved sync profiles for recurring music transfers
• Edit metadata including title, artist, album, genre, year and track number
• Preview local audio files
• Manage and delete tracks on the device
• Warn when the device is disconnected or powered off
• Show transfer progress with automatic and manual notification dismissal
• Follow the system light or dark theme
