Original submission:

I would like propose one very useful patch:
When the cursor is at directory and You press F3,
midnight commander display size of all files in directory.

It could be display in column "size", or at down of the screen.
What do You think about this idea ?
I think its very useful.

FAR Manager (http://farmanager.com/) uses contains this feature too.

Comment 3 by Felix Miata <mrmazda> at Sat 05 Mar 2005 01:16:17 PM UTC:

FC/2 & FC/W performs this function with Ctrl-Q. I use it all the 
time.

Comment 4 by Coenraad Loubser <tunasashimi> at Tue 19 Apr 2005 10:28:27 PM UTC:

I think it is a very stupid idea since F3 means VIEW and has since 
Norton Commander V1.

It would however be a useful feature... moreso than the tree view.

Comment 5 by Roland Illig <rillig> at Sat 28 Jan 2006 08:56:14 AM UTC:

This feature exists in the current development version. Press 
C-space.

Comment 6 by Leonard den Ottolander <leonardjo> at Mon 27 Feb 2006 10:09:02 PM UTC:

Reopening.

It would be nice if this could be toggled back, and maybe C-space 
shouldn't move down...

Comment 7 by Pawel Misiak <pavelsky> at Tue 16 May 2006 05:59:54 PM UTC:

It works with C-space as expected, move-down is ok, I need it 
working that way. Maybe F3 on some dir shouldn't move down. Besides,
is there any shortcut to recalculate sizes of all subdirs in current
panel? I would be great to have one.

Comment 8 by Roland Eggner <robiol262> at Mon 25 Dec 2006 03:23:40 PM UTC:

For me the most useful solution to this issue would be, if tagging 
of one or more directories would trigger calculation and displaying 
of the size of the trees below them. TC for a well known proprietary
OS provides this feature.

A keybinding to recalculate sizes of ALL directories in current 
panel would be very useful addition to the menue entry we already 
have, I agree to Pawel.

I'm also propose F3 to recalculate size for selected items if any files/directories selected and
focus on directory (so that not break F3 for view file).

Far Manager has the same behaviour, and F3 should not change directory if files/directories selected.

In this we will need to place an option, what should F3 do. We already have such a proposal, but a couple of people were against new behavior. And in the sight of configurable hotkeys: we can add an action, which can be assigned by the user to any key he wish to.

It will not break old behaviour but just extend it (in case of selection).
We can speak about configurable hotkeys after pre2 when it will be ready.

[iNode]

ok. Final decision from discussion in jabber conference:
F3 save it's behavoiur. New behaviour will be on C-space.
C-space should work in that manner:

• if there is no selected dirs - work as usual, except ".." - calculate all dir sizes
• if there is selection - calculate size for it

in the end panel should be resorted.

hmm, just a random thought: i'd like to see c-space to be used instead of (or alternatively to) m-tab for completion (as m-tab typically conflicts with window switching in x environments, and c-space means complete in most IDEs).
i wonder whether it would be ok to use space without any modifier for the show size thing, but only if the command line is empty - +/-/* already behave that way.

It's good idea. We also has free M-space, AFAIK.
So we can remap it before it become habitual, or
use M-space for completion.

[ossi]

m-space is often also taken by the window manager to pop up the window's system menu (in kde, it is alt-f3 by default, but m$ windows uses m-space and so do some others).

additional patch to avoid resort if panel sort type is not size

please, review

Branch: 7_show_dir_sizes (parent: master)
Changeset: e1120731a9744009560aedb19f5a3961291f0e51, 8cda5a9629b96fc3112091bb5a6736210891534c

Added a small usability enhancement: when the cursor is positioned on a regular file and “Show directory sizes” command is invoked or C-Space is pressed, the sizes of all directories in the current working directory will be computed as if the cursor was positioned on “..”.

This is a very intuitive behavior and it absence actually caused quite a bit of confusion (e.g. see Ubuntu bug LP#580221).

​https://bugs.launchpad.net/ubuntu/+source/mc/+bug/580221

Renamed the menu item Show directory sizes to Show directory size(s) to emphasize its new meaning (in comparison with 4.6 branch). Previously this menu item would compute the sizes of all directories regardless of the selection and currently active item. Now by default it computes the size of the currently active directory, unless there's a selected or user is on “..”.

Comments and discussion is welcome.

[zaytsev]

What about reviewing this one? The branch was created two months ago...

[zaytsev]

See discussion in #2088. Shall we additionally decouple the menu from the shortcut?

[zaytsev]

Ok, these enhancements are going to be implemented in #2088 along with the other changes.
