DFSee 12.3 released; Performance improvements

February 01, 2015 by jvw@dfsee.com

DFSee version 12.3 has been released, with performance improvements and fixes.


It is a MINOR release, with several small fixes and enhancements, but
most of all, a HUGE performance improvement for file recovery.


Searching for normal/deleted files has been sped up by a factor of 100
or more for most filesystems, by restricting the search to areas known
to contain directory information (including Inodes, Fnodes, MFT-records)
Instead of searching for several hours on a large volume, it will find
all the files in existing directories within a few minutes.


Using the '-d-' option or 'Search Outside Dir/Fnode/Inode/MFT area too'
checkbox will revert to the older much slower search method, but will find
ANY file, even if it is not inside the currently present directory areas.



DFSee is a very powerful disk-utility with disk partitioning,
filesystem and disk analysis, some file recovery and UNDELETE
and smart imaging or cloning of partitions or complete disks.
