Thunar vs jFileProcessor

Unlike Nautilus, which requires the whole GNOME desktop, thunar just depends on some XFCE utilities & GTK.

While in a Thunar window, typing either a "~" or a "/" will automatically start typing into the "address-bar" and pressing enter goes straight to the typed directory.

In a thunar window, any non-directory typing will search in the current directory for the filename that you type (non-recursive, unlike Nautilus)

Select multiple files in the current folder using a wildcard pattern.

Use Custom Actions to add right-click options to do things like Open as Root, Open Git GUI, etc. You can filter the file types and filename patterns that the actions will show up for.

To add an "Open as Root" action, go to Edit, Configure custom actions. Assign a name and a description. Set Command as "gksudo xdg-open %f" (you'll need to install gksudo since pkexec won't work). Pick an icon (I prefer "changes-allow"). Under Appearance Conditions, select Directories, Text Files, and Other Files.

Supports the M4 and M5 mouse buttons for forward/back, similarly to most browsers.

With also predefined functions as insert (date, numbering,...), search/replace, etc ...

Browse files in two directories with a dual pane view.

But nothing more.

While in a Thunar window, typing a filename automatically selects the first matching file in the current folder.

Thunar can use the editable accelerator feature of XFCE.

Run xfce4-appearance-settings in terminal, go to settings tab, check "enable editable accelerator". Now open any command in Thunar menu, hover to a command, i.e. your custom "places" or your custom command, then press any combination to assign a shortcut to it.
be careful though, cause it will also remove the shortcut from other command.

Use tabs to open fewer windows. New tabs automatically start in the same location. Tabs can be detached.

Find/select files in sub-folders. run touch %f or cp %f /somefolder (this is a way to copy selected files in different levels, into 1 folder, flattening out the copy).

Select files. regex to match pieces of filenames, rename adding, leaving out, and reusing saved pieces.

So you can watch a folder and process files that come into it.

With exact file you can create a folder of job or desktop icon names. Double-click that file to run the job since it is tied to just that specific file.

Your script can modify contents in the list window it is working on.

Just put groovy scripts in menu-scripts folder and they will automatically run using currently selected files.

Run commands on your lists: grep files to find stuff, delete/copy/move files, etc.. Even copy a file to a remote host and execute it.

Search files and save to another file or a list window. Add or subtract one list from another.

Just count matching search criterion.

Search on modified time, file size, glob/regex name, folder depth; and/or on these and can do range.

Available for Linux, Windows, macOS - just needs java 7+ (written with 8).
