The ls output is showing the size of the files listed (note that a directory is just one type of a file).
The du -hs output is showing the sizes of the blocks allocated to the file and (when the file is a directory) the size of the blocks allocated to the directory added to the sizes of the blocks allocated to all files in the file hierarchy rooted in that directory. Note also that the sizes of files in a file hierarchy reported by du -hs might not be what you expect. If there are hard links to files in a hierarchy, the blocks allocated to each linked file will only be counted once. Therefore, the sum of the sizes reported by:
might not be the sum of the sizes reported by:
And, if there are sparse files, the file size may be huge, but the number of blocks allocated to the file may be tiny.
And note that the size of a directory varies from filesystem type to filesystem type. On some filesystem types, the size of a directory shown by ls will be the size of the directory entries in that directory; in other filesystem types, it will just be the number of directory entries contained in that directory; and in other filesystem types, it might be something else. (On some filesystem types, some directory entries can be stored in the i-node for the directory. This makes the size of the directory zero until enough space is needed by directory entries to overflow the space in the i-node.)

folders
folders(1mh)folders(1mh)Name
folders - list folders and contents
Syntax
folders [ +folder ] [ msg ] [ options ]
Description
The command displays the names of your folders and the number of messages that they each contain.
The command displays a list of all the folders in your Mail directory. The folders are sorted alphabetically, each on its own line. This
is illustrated in the following example:
Folder # of messages ( range ); cur msg (other files)
V2.3 has 3 messages ( 1- 3).
adrian has 20 messages ( 1- 20); cur= 2.
brian has 16 messages ( 1- 16).
chris has 12 messages ( 1- 12).
copylog has 242 messages ( 1- 242); cur= 225.
inbox+ has 73 messages ( 1- 127); cur= 127.
int has 4 messages ( 1- 4); cur= 2 (others).
jack has 17 messages ( 1- 17); cur= 17.
TOTAL= 387 messages in 8 folders.
The plus sign (+) after inbox indicates that it is the current folder. The information about the folder includes the term (others). This
indicates that the folder contains files which are not messages. These files may be either sub-folders, or files that do not belong under
the MH file naming scheme.
The command is identical to the effect of using the -all option to the command.
If you use with the +folder argument, it will display all the subfolders within the named folder. as shown in the following example:
% folders +test
Folder # of messages ( range ); cur msg (other files)
test+ has 18 messages ( 1- 18); (others).
test/testone has 1 message ( 1- 1).
test/testtwo has no messages.
TOTAL= 19 messages in 3 folders.
See for more details of sub-folders.
Options-fast
-nofast Lists only the name of folders, with no additional information. This is faster because the folders need not be read.
-help Prints a list of the valid options to this command.
-list
-nolist Lists the contents of the folder-stack. No +folder argument is allowed with this option.
-pack
-nopack Re-numbers messages in the folders. Messages are re-numbered sequentially, and any gaps in the numbering are removed. The
default operation is -nopack, which does not change the numbering in the folder.
-pop Discards the top of the folder-stack, after setting the current folder to that value. No +folder argument is allowed with this
option. This corresponds to the operation in the C-shell; see The -push and -pop options are mutually exclusive: the last occur-
rence of either one overrides any previous occurrence of the other.
-push Pushes the current folder onto the folder-stack, and makes the +folder argument into the current folder. If +folder is not
given, the current folder and the top of the folder-stack are exchanged. This corresponds to the operation in the C-shell; see
The -push switch and the -pop switch are mutually exclusive: the last occurrence of either one overrides any previous occurrence
of the other.
-recurse
-norecurse
Lists folders recursively. Information on each folder is displayed, followed by information on any sub-folders which it con-
tains.
-total
-nototal Displays only the total number of messages and folders in your Mail directory. This option does not print any information about
individual folders. It can be suppressed using the -nototal option.
The defaults for are:
+folder defaults to all
msg defaults to none
-nofast
-noheader
-nototal
-nopack
-norecurse
Restrictions
MH does not allow you to have more than 100 folders at any level in your Mail directory.
