ls command or the
Win32 dir shell commandThe index of a directory can come from one of two sources:
index.html. The The two functions are separated so that you can completely remove (or replace) automatic index generation should you want to.
Automatic index generation is enabled with using
Options +Indexes. See the
If the FancyIndexing option is given with the SuppressColumnSorting
option.
Note that when the display is sorted by "Size", it's the actual size of the files that's used, not the displayed value - so a 1010-byte file will always be displayed before a 1011-byte file (if in ascending order) even though they both are shown as "1K".
Various query string arguments are available to give the client
some control over the ordering of the directory listing, as well as
what files are listed. If you do not wish to give the client this
control, the IndexOptions
IgnoreClient option disables that functionality.
The column sorting headers themselves are self-referencing hyperlinks that add the sort query options shown below. Any option below may be added to any request for the directory resource.
C=N sorts the directory by file nameC=M sorts the directory by last-modified
date, then file nameC=S sorts the directory by size, then file

FancyIndexing.
File is a file extension, partial filename, wild-card
expression or full filename for files to describe.
If String contains any whitespace, you have to enclose it
in quotes (" or '). This alternate text
is displayed if the client is image-incapable, has image loading
disabled, or fails to retrieve the icon.

MIME-encoding is a valid content-encoding, such as

This alternate text is displayed if the client is image-incapable,

This sets the description to display for a file, for
FancyIndexing.
File is a file extension, partial filename, wild-card
expression or full filename for files to describe.
String is enclosed in double quotes (").
The typical, default description field is 23 bytes wide. 6
more bytes are added by the IndexOptions SuppressIcon option, 7 bytes are
added by the IndexOptions SuppressSize option, and 19 bytes are
added by the IndexOptions SuppressLastModified option.
Therefore, the widest default the description column is ever
assigned is 55 bytes.
Since the File argument may be a partial file name,
please remember that a too-short partial filename may match
unintended files. For example, le.html will match the
file le.html but will also match the file
example.html. In the event that there may be ambiguity,
use as complete a filename as you can, but keep in mind that the
first match encountered will be used, and order your list of
AddDescription directives accordingly.

Descriptive text defined with
Absolute paths are not currently supported and do not match anything at runtime. Arguments with relative path information, which would normally only be used in htaccess context, are implicitly prefixed with '*/' to avoid matching partial directory names.
This sets the icon to display next to a file ending in
name for FancyIndexing. Icon is either a (%-escaped)
relative URL to the icon, a fully qualified remote URL, or of the format
(alttext,url) where alttext
is the text tag given for an icon for non-graphical browsers.
Name is either ^^DIRECTORY^^ for directories,
^^BLANKICON^^ for blank lines (to format the list
correctly), a file extension, a wildcard expression, a partial
filename or a complete filename.
^^BLANKICON^^ is only used for formatting, and so
is unnecessary if you're using IndexOptions
HTMLTable.

content type of text/* (e.g.,

NTFS volumes. OS2 and Win32 FAT volumes, for example, do not.
Once this feature is enabled, the client or proxy can track
changes to the list of files when they perform a HEAD
request. Note some operating systems correctly track new and
removed files, but do not track changes for sizes or dates of
the files within the directory. Changes to the size
or date stamp of an existing file will not update the
Last-Modified header on all Unix platforms.
