FreeCommander is a file manager for Windows. It supports dual-panel, tabbed interface, an optional tree view for each panel, a built in file viewer to view files (hex, binary, text or image format), a
file viewer inside archives, built in FTP client, access to system folders, control panel, desktop and start menu; copy, move, delete, rename files and folders; a multi rename tool. I can also create and verify MD5 checksums, split files, edit file properties, calculate folder size, compare folders, synchronize folders, search file searching (inside archive too).
