Respected readers welcome, After using several programs i discovered Xyplorer, it has all the features which many of them where missing.Even Total commander hasn't got some of them like Undo/redo,customizable keyboard shortcuts etc...Directory opus also fails in comparison to this in easy usage. The greatest things are that i am discovering new features every month and the developer of Xy -- "Donald" improves Xy daily. Main features-- 1) Dual pane file manager with tabs. 2) Queued file operations. 3) One-click previews of all important image, audio. 4. Undo/redo of file operations 5. Customizable keyboard shortcuts. 6. Powerful file search. Also one can set single key shortcuts for back/forward like "[" for back and "]" for forward, usually in win explorer this happens by alt+left arrow/right arrow.Set "/" for root of the folder,which takes u to d: or c: even though one is in deep sub-folders. raama--raama from india.
