Alright, so you were browsing a folder or were running an important application and it got closed by mistake, what will you do? Panic, of course. But don’t fret yet, ReOpen is a free portable tool for Windows that can restore all accidentally closed programs, folders, files, etc. It sits silently in the system tray and takes very less system resources.
To restore an accidentally closed program, you can either double-click the system tray icon or hit the Hotkey(Shift+PgUp). This will open the main window, where you can select the program that you want to restore and hit Open Selected.
The main window contains two sub-windows, the one above is for folders, while the one below is for closed files and programs. To change the hotkey, right-click the system tray icon and select Set Hotkey.
