A dual-panel file manager for macOS that lets you conveniently handle files across cloud storage providers.

• Dual-panel file browser — navigate two directories side by side, copy and move files between panels with keyboard shortcuts
• Multi-cloud support — connect multiple cloud storage accounts and browse them directly alongside your local files
• Cloud-to-cloud transfers — conveniently move or copy files between cloud providers
• Sync Mode — new in 0.9 — mirror, newer-only, or additive sync between any two folders (local or cloud), with a pre-flight plan that calculates file counts, total size, and direction before a single byte moves
• Byte-level progress bar — new in 0.9 — transfer progress is weighted by bytes rather than file count, so a single large file doesn't stall the bar; every active transfer has a Cancel button with confirmation
• Conflict resolution — when files already exist at the destination, a side-by-side comparison shows both files with dates, sizes, and newer/older labels, plus Apply to All, Stop, Skip, Keep Both, and Replace actions
• Universal search — search across all local files and connected cloud accounts at once, with results grouped by source and right-click to open in either panel
• Native performance — built with SwiftUI and AppKit for a fast, responsive experience on macOS
• Quick Look previews — preview files inline without leaving the app
• Keyboard-driven workflow — navigate, select, copy, move, rename, and delete with shortcuts
• Folder size calculation — calculate folder sizes in the background without blocking the UI
• Favorites — pin frequently accessed local and cloud folders to the sidebar
• Hidden files toggle — show or hide hidden files per panel
• Automatic Google Workspace conversion — Google Docs, Sheets, and Slides are automatically converted to DOCX, XLSX, and PPTX when transferring to local folders or other cloud services
• Preserved modification dates — files transferred from cloud storage retain their original modification dates
