DFSee 12.1 released: EXFAT support, enhancements and fixes

September 11, 2014 by jvw@dfsee.com

DFSee version 12.1 has been released, with new functionality and several fixes.

It is a MINOR release, with support for the EXFAT filesystem as the
main added feature, and several other small enhancements and fixes.

EXFAT is a 32-bit FAT filesystem optimized for (very large) removable media
like SD-cards used with cameras. It has an additional allocation-bitmap that
avoids a lot of the normal overhead when writing contiguous files. It is
now supported by Windows, OS-X and Linux, and is the recommended filesystem
for SD-cards larger than 32Gb.

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.
