+ File system.
+==============
+
+Make label on FAT32 volume.
+===========================
+
+The volume name can be up to 11 characters long::
+
+  $ sudo mlabel -i /dev/<device> ::my-label
+
+or when create FAT32 file system::
+
+  $ sudo mkdosfs -n <vol-name> /dev/<device>
+
+Convert file name coding.
+=========================
+::
+
+  $ convmv --nosmart -f cp-1251 -t utf-8 -r $dir
+
+How get file time attributes.
+=============================
+
+POSIX define 3 file time attributes: atime (access time, only a few OS/fs update
+this parameter), ctime (attribute/inode modification time), mtime (modification
+time).
+
+To get time you can use 'ls' command but it print time in locale dependent
+irregular form::
+
+  $ ls -l file.txt      # last file modification
+  $ ls -lc file.txt     # last file status modification
+  $ ls -lu file.txt     # last access
+
+GNU coreutils provide more robust 'stst' utility::
+
+  $ stat -c %Y file.txt # last file modification
+  $ stat -c %Z file.txt # last file status modification
+  $ stat -c %X file.txt # last access

+How get UUID and label?
+=======================
+
+Include UUID (Universally Unique Identifier) and labels::

+
+Ext2 IFS.
+---------
+
+It provides Windows NT4.0/2000/XP/2003/Vista/2008 with full access to Linux Ext2
+volumes (read access and write access). This may be useful if you have installed
+both Windows and Linux as a dual boot environment on your computer.
+
+The "Ext2 Installable File System for Windows" software is freeware.
+
+After install use 'ifsdrives.cpl' control panel to modify settings.

+rfstool.
+--------
+
+Allows you to access ReiserFS partitions from a Windows 95/98/ME/NT/2000/XP
+system. It also allows you to access ReiserFS partitions from Linux. It is a
+complete rewrite of the ReiserFS functions needed to list directories, copy
+files, and backup metadata.
