DirDeck turns file management on Mac into a focused workspace. Browse with tabs, save named Workspaces, put folders side by side in 12 pane layouts, and keep each pane's history and view state. Super Preview looks inside folders, archives, documents, spreadsheets, images, media, and 100+ formats. Preview batch renames, edit images, work with PDFs, search Finder Tags, and park files in File Transit. Everything stays on your Mac, with no DirDeck account required.
