Current information about changes in Hetman Software products

28.08.2023

  • A number of minor bugs FIXED.

25.07.2023

  • FIXED. MBR: sometimes, excessive disks were identified and added (by mistake).

  • FIXED. Interface: on some monitors, icons for deleted files and folders weren’t displayed correctly.

14.07.2023

  • FIXED. MBR: fixed MBR table read error (it used to occur when a physical MBR disk had many logical partitions).

  • FIXED. ReFS: in some cases, the program failed to display file contents.

  • LVM. Thin Provisioning: added support for Tier Thin Pool technology (previously, only Thin Pool was supported).

  • XFS: improved support for large files and sparse files.

30.03.2023

  • FIXED. From time to time, the program tended to freeze suddenly while scanning the disks.

  • FIXED. VMFS: the program sometimes froze at startup (while reading data from VMFS).

  • FIXED. HFS+: in some cases, the program froze while analyzing the file system.

  • FIXED. XFS: On some systems, the block size was misidentified so the system was either not analyzed at all or analyzed incorrectly.

27.12.2022

  • FIXED. ZFS file system: in some cases, the program failed to find all files with Fast scan.

12.12.2022

  • GPT: when the inner disk table (inside GPT) is damaged, the program will read its copy.

  • FIXED. Saving disk analysis data: there used to be an error when users saved Full scan and Content-Aware scan data and then opened it.

5.08.2022

  • FIXED. ReFS: in new versions of this file system, file contents were not displayed;

  • FIXED. XFS: fixed the error in analyzing old versions (4 and earlier). Previously, analysis of some systems was not supported;

  • XFS: improved analysis algorithm. In some cases, the file contents which were not displayed before are now shown properly;

  • FIXED. XFS: some deleted files were displayed as existing;

  • FIXED. Ext3/4: when running Fast scan, the program might freeze in some cases;

  • During registration, it is now possible to enter the key both with hyphens and without them.

15.07.2022

  • ZFS: added 4K block support;

  • FIXED. NTFS: in some situations, found files were duplicated;

  • Improved support for mounted disks: when a mounted disk is removed, the remaining disks related to it are checked (for example, its child disks created automatically with RAID or LVM), and they are removed (only if all their parent disks are removed).

7.06.2022

  • XFS: scan algorithms improved (for both quick scan and full scan). Now the program shows properly more of the files, which used to be recognized as having zero byte size;

  • APFS: fixed errors in working with disks containing Snapshots;

  • FIXED. UFS: with quick scan, the program could almost freeze in the process (i.e. it would take a really long time to analyze a disk);

  • LVM: added LVM Thin Provisioning support;

  • Thumbnails and Preview: now the program can identify text documents regardless of the file extension;

  • Preview: added HEX mode. It is displayed automatically if the program can’t show the file contents in the conventional way. This can be disabled in the program settings;

  • FIXED. Mounting disk images: in some cases, physical disks were displayed as logical;

  • Saving files by FTP: accelerated, added support for big files, added support for UTF8 servers;

  • Saving disk images: added the option to save an image to FTP server.

14.04.2022

  • Ext3/4. Improved journal analysis algorithm: as a result, the program now displays contents for a larger number of deleted files;

  • Ext3/4: in some cases, the Fast scan process has been accelerated considerably;

  • FIXED. XFS: in some cases, the program misinterpreted file structure and therefore failed to display some files and folders.

22.07.2021

  • NTFS: added journal analysis;

  • FIXED. Ext3/4: the program tended to find many odd files with non-existing and/or unreadable names.

1.07.2021
