* 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

* File names.

* Block device attributes.

** How get UUID and label?

Include UUID (Universally Unique Identifier) and labels.

** How set UUID and label?

For ext2/ext3 fs:

  $ sudo tune2fs /dev/hdb1 -U `uuid`

* Linux fs under Windows.

** 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.

** Ext2Fsd.

Ext2Fsd is an open source linux ext2/ext3 file system driver for Windows systems (NT/2K/XP/VISTA,
X86/AMD64).

** 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.
