cfv vs Double Commander

Will access .gz files as gzipped. Can create gzipped files.

-n will rename bad files based on --renameformat.

Cfv shows a progress bar when working so you know that the process is actually taking place.

Runs on all systems Python supports. It has been verified to work on Linux, FreeBSD, OpenBSD, NetBSD, Solaris, OS X, and Windows.

cfv offers 2 recursive modes: -r will make separate chksum files for each dir and -rr will create a single file.

You can use same tool in all desktop OS environments.

If the developer loses interest there is at least the possibility that someone else will pick up the torch.

Lots of options allow you to configure DC the way it suits you best: Tools, Fonts, Colors, Hotkeys, Mouse, Fileviews, Plugins, Layout, Toolbars, Tabs, Icons etc.

Save shortcuts to folders. Organize them in a treeview with submenus. Define a name and sorting for each entry.

so you can use documentation from Total Commander for writing plugins. WCX (packer), WDX (content), WFX (file system), WLX (lister).

For instance, the 'Settings | Layout' pane is quasi-identical to TCs.

Although it is lightweight and simple to use, it can do very sophisticated tasks, like copying files from directories which have a certain extension or file size or have a certain text pattern in them. Also, it's very customizable and stable.

It's all a matter of perspective. I'm not for an argument about IDE's, frameworks etc, but to me that's a big plus. I think it should be a tie, it's either a pro or a con or should that be neither a pro nor a con. It just depends on context.
