Options common to all filsystems

ZAR has been discontinued
After about twenty years, I felt ZAR can no longer be updated to match the modern requirements, and I decided to retire it.

ZAR is replaced by Klennet Recovery, my new general-purpose DIY data recovery software.

If you are looking specifically for recovery of image files (like JPEG, CR2, and NEF), take a look at Klennet Carver, a separate video and photo recovery software.
Quick scan mode

In certain cases, ZAR data recovery software can recover a filesystem without a need to perform a full scan of the volume. This may provide significant (up to ten times) speed boost compared to the traditional "read all" analysis.

Quick scan mode activates automatically if certain conditions are met. It works with NTFS volumes only. If ZAR detects that the data gathered during the quick scan is not enough for a filesystem reconstruction, it reverts to the full scan automatically.

Quick scan mode is inhibited if any of the following conditions are met:

  • RAID or Digital Image recovery run is performed.
  • The filesystem type override is in effect and the specified filesystem type is not NTFS.
  • The partition to scan is smaller than 8GB.

Default setting is Automatic. When set to Disabled, quick scan mode will not activate regardless of the volume condition.

You should disable quick scan mode if you are recovering FAT volume which was accidentally formatted to NTFS.

Cluster size detection
This parameter is deprecated and only available for compatibility reasons. Leave it at the default value.
Filter empty files and folders
With this option enabled, empty (sized 0 bytes) files and empty folders (containing no files and subfolders) will be filtered from the results.
Filter duplicate files
When enabled, the files with the fully identical content residing in the same directory will be filtered so that only one remains. This reduces the number of files requiring manual review after the data recovery.
