The best ever Windows file manager program that I’ve used is WinNc. There is a trial version that runs an unlimited amount of days.
It’s modelled after the DOS Norton Commander, if you remember that, and came out right after NC was no longer available. It’s kept the same two-panel format over the years and has upgraded from at least Windows 3.0 (or maybe even earlier, I started using it in Windows 3.0) and is now Windows 11-ready. The developers are in the Netherlands.
I use it primarily to synchronize my laptop with my PC. But, I’ve found it useful for comparing folders or files (including text files), and changing time stamps. You can also compress, decompress, create a self-extracting file, encrypt, decrypt, zip and mail, split files, merge files. It has commands for searching, renaming, editing, viewing, copying, moving, creating a new folder, deleting, calculating file size, creating a file list, saving a MP3 playlist, undoing, redoing, and more.
At the top of the screen across the two panels, you can create tabs and pin them for whatever two-panels you want to work with. You can also create tabs at the top and/or the bottom of each panel for whatever folder you want to show up in the panel. You can save your configuration and load or reload configurations at will.
At the top of each panel are navigation tools (back, forward, up, Documents, Desktop, Favorites, Drive, Network path, FTP) and at the bottom of each panel are tools for selection, deselection, refreshing, setting the path, and panel search.
It can be easily customized for Theme (various versions of Windows, Total Commander, Norton Commander, FreeCommander), Layout , Visual features (for toolbars, colors, presence or absence of tabs, colors, tab style, 16 different languages), Settings (search options, quick access options, synchronize options, undoing deletion to the recycle bin, turning off confirmation dialogs, setting the active panel for synchronization, file associations, ), Panel options (using a long time format, file size display, strict file compare time, natural sort order,…)
