Ext2 Installable File System For Windows - драйвер, позволяющий производить на разделах с файловой системой Linux Ext2 или Ext3 операции чтения / записи и практически любые другие, кроме изменения прав доступа и дефрагментации. Реализован на уровне ядра, поэтому после его установки все win32-программы смогут иметь прямой доступ к разделам Ext2 или Ext3.
Features:
• Supports Windows NT 4.0, Windows 2000, Windows XP, Windows 2003, Windows Vista and Windows 2008.
• Supports both the 32 bit x86 and the 64 bit x64 platform.
• Includes drivers with a digital signature for Windows Vista x64.
• All operations you would expect: Reading and writing files, listing directories, creating, renaming, moving and deleting files or directories, querying and modifying the volume's label.
• UTF-8 encoding.
• Files larger than 2 GBytes.
• Supports hash indexed (htree) directories (utilizes the so-called dir_index feature of Ext3).
• Full plug-n-play functionality. When a drive is removed, the corresponding drive letter is deleted.
• Supports use of the Windows mountvol utility to create or delete drive letters for Ext2 volumes (except on Windows NT 4.0). This is useful for scripts.
• A global read-only option is provided.
• File names that start with a dot "." character are treated as hidden.
• Supports GPT disks if the Windows version used also does.
• Paging files are supported. (A paging file is a file "pagefile.sys", which Windows swaps virtual memory to.) Users may create paging files at NT's • control panel at Ext2 volumes.
• Specific functions of the I/O subsystem of NT: Byte range locks, notification of changes of directories, oplocks (which are required by the NT LAN manager for sharing files via SMB).

The file system driver Ext2fs.sys caches file data and the file system's meta data such as directories and all the on-disk structures of the Ext2 file system. (It uses the file cache of the Windows NT operating system.) Therefore it is performant. The level of sophistication of the Ext2 file system driver's implementation is indeed comparable to Windows NT's native file system drivers.

The "Ext2 Installable File System" software package is distributed as a single executable solution, complete with all of the features. It is a setup wizard which installs and configures the Ext2 file system driver. If you wish to uninstall the software, select "Add/remove Software" from the Control Panel.

Furthermore, "IFS Drives" is installed at the computer's control panel, which allows you to assign drive letters to Ext2 volumes.
