If you just want your list of files recursively that reside under a specific directory, and do not mind dropping to a terminal to get it, you have the following options.
$ ls -R <somedir>
$ find <somedir>
$ tree <somedir>
But these are not interactive in any way, as if they were displayed by a file browser, rather they're just a static listing of the files that reside under
<somedir> and the sub-directories underneath too.
There are many GUIs for exploring files within Unix/Linux, and I'm just not that up on all of them, unfortunately. So rather I'll explain how I'd go about finding an alternative.
Whenever I'm looking for a tool that does similar things to an existing tool I'll first start by going to Alternative To. NOTE: Be sure to go to the
.net site, there are knock-offs.
From here you can search for tools that others have identified as alternatives to tool X. When searching here I like to start with a specific tool, but then take a few of the results and put them into the site as well, to cast my net even wider. So for today I'd put in your "Total Commander" tool along with say "Nautilus".
Here's the search for Linux alternatives to "Total Commander": http://alternativeto.net/software/total-commander/?platform=linux.
Here's the search for Linux alternatives to "Nautilus": http://alternativeto.net/software/nautilus/?platform=linux
I'd comb over these lists of applications, looking for any that possess the ability to show you all the files recursively in directory X.
I did come across this blog post titled: XTREE branch view (aka “flat VFS” or Flat View) capability in Linux / Ubuntu file managers. This article has someone who's looking for the exact same feature as you.
I’m researching Linux file managers which implement a famous
XtreeGold file manager feature commonly known as branch view,
flat view, or “flat VFS.” A branch view of a directory will show, in
one panel, both a parent directory’s files and all its subdirectory
files. In principal, one can view, sort, filter, and issue a command
on files which originate from different directories. Of course, such
recursive operations can also be accomplished in a less visual way
using many command line tools.
Unfortunately no popular Linux GUI file manager includes a branch view
display feature- and few file manager developers seem to be aware of
(or discuss) this flexible approach to viewing and managing groups of
files. Krusader and others do implement special virtual file
system panels (e.g., display/ manipulate archive file contents, or
manipulate file search results in a panel), but not a basic branch
The "Flat View" that you're looking for appears to go by several names. I found this page titled: Less is More: Orthodox File Managers as Sysadmin IDE which had the following blurb about the topic:
XTree or "Flat tree" VFS. Most modern OFMs provide the possibility of viewing all files in a branch of the tree in a "flat" representation (often bound to Ctrl-B). This representation is extremely important for working with files dispersed into several directories as is often the case in most application installations.
