• New user interface to compare two folders and see the file comparison status for each file.
• New user interface to view logs for synchronization, backup, real-time mirroring, error/warning messages, and list of currently opened files for real-time mirroring. Logs are updated in real-time.

• Synchronization routine now uses a temporary file for copy operation to avoid existing mirror file deletion problem in case the file could not be copied due to some unexpected error.
• Support for synchronization/mirroring of sparse files without removing its sparse attribute if mirror drive supports sparse file, i.e., if both source and mirror drives are formatted with NTFS and running Win2000 or higher.
• It is now compatible with data execution protection feature of WinXP SP2, Win2003 server, or higher.
• Limit for setting maximum seven mirrors per source folder has been removed.
• You can now create additional mirror(s) for a subfolder under an existing source folder without first excluding that subfolder for mirroring under the source folder.
• New "Instant Synchronization" mode for monitoring file changes in real-time and replicating them as soon as they happens.
• Support for synchronization at logon and logoff.
• Better management of user account and additional network logon option to perform the synchronization/backup under a specified user's account.
• Additional file comparison methods for synchronization.
• New synchronization option using NTFS Change Journals records.
• New option to replicate file delete operations in bi-directional mode.

• Does not try to copy Outlook's ".pst" file(s) if they are opened (otherwise, the mirror file was getting deleted if there was any error during copying the opened .pst file).
• Fixes a problem causing creation multiple network sessions for the same network shared folder under some condition.
• Now it does not check for the "temporary" attribute of a file as this attribute is not consistently set by the application software to mark a file as temporary.

• Fixed a problem that was causing hang when saving file from MS Word 2003.

• Fixed a bug of skipping files with zero attribute during initial synchronization.
• Added few more error reporting when remote mirror is not available or can't be accessed.

• Moved log files under Windows common data folder so that it can be updated even when synchronization is running under a non-administrator account on NT-based systems.
• Provided an option ("NoDefaultStartupSync") in the registry to disable default synchronization of all real-time mirror folders on startup (see FAQ).
• MirrorFolder will now ask for the user's confirmation if it finds an existing file in the mirror folder has more recent last modified time stamp during initial synchronization.
• Fixed a bug in comparing last modified time stamp of the source and mirror files when mirroring from a NTFS drive to a FAT32 drive in real-time mode. Now our real-time mirroring driver will only update the mirror file (before opening both files for real-time mirroring) only if last modified time stamp difference is greater than 2 seconds. Earlier it was less than 2 seconds causing unnecessary copying of the source file whenever it was opened for real-time mirroring.
• Few others bugs have been solved when MirrorFolder is running under a non-administrative account on NT-based systems.
• Does not reset the attributes of subfolder if "Copy file/folder attributes" is disabled, i.e., it leaves the attributes of the subfolder as it is.
• Fixed a bug that was causing hang under some condition during folder comparison.

• Fixed problem of not showing mirroring option and generating fault during startup when MirrorFolder is running under non-Administrator account on WinNT/2K/XP/2k3.

• Fixed error "This function is only valid in Win32 mode" while copying file on Win98/Me.
• Disabled "Synchronize on shutdown" option on WinNT 4.0 as required support is not available on this OS to implement this feature.

• New major release.
