One to four content panes
Open multiple folders in one window and adjust the workspace for focused sorting, comparison, and transfer tasks.
SpacePiece
A macOS file manager for arranging folders side by side, sorting files quickly, comparing changes, and moving work between local and supported server locations without losing context.
Built for multi-pane file work
Per-pane tabs
Keep related folders grouped inside a pane, move tabs between panes, and close panes naturally when their tabs are done.
Transfer queue
Track copy and move operations with progress, errors, and a sequential queue mode for slower or external drives.
Saved workspaces
Keep pane layouts, tabs, and favorite locations ready for repeated project and cleanup workflows.
Compare & Sync preview
Review differences between local folders before choosing copy, move, match, or cleanup actions.
Connected servers
Add supported server and cloud locations so remote file work can live beside local folders.
Local-first by design
SpacePiece works with files on your Mac and attached volumes first. When you add a supported server or cloud connection, SpacePiece uses that connection only for the file operations you request.
