File copying

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.
Selection info
This section displays number and size of the selected directories and files. You may want to check the total file size with respect to the free space available on your target drive. It is not unusual to get a slightly larger amount of data than expected. This effect arises when multiple file versions (previously erased files) or duplicate files (e.g. when the file was moved, it may be recovered in both old and new locations) are being restored.
Specify the target folder (where the recovered files will be placed). You may type the folder name, or browse for it using "..." button. ZAR will check that the path specified does exist and is writeable.

WARNING: Avoid copying data onto the same physical device you are recovering data from. This may induce additional data loss. The following considerations apply:

  • If there is some physical damage involved, any additional load on the disk may cause further damage.
  • If logical structures are corrupt, damage cascading effects may occur during writes on the volume.
Existing files handling
"Overwrite" setting is not recommended for general use because of the following side effect: if there are multiple files with the same name in the same folder (typically several file versions - the latest one plus several previously erased versions), an arbitrary one will be picked, possibly overwriting the good file (with an older version in the above example).
Progress indication
The progress bar displays a percentage of total data size processed. File information displays number of files copied and the name of the file under processing.
"Start copying" button
Obviously, this button starts copying files to the target location.
"Skip current file" button
Forces ZAR to skip the current file. Partial files are not deleted but left on the target.
Flushing the disk cache
Once file copying is finished, the window may appear indicating that the disk cache is being flushed. This may take considerable amount of time if "Write cache" setting in options is configured for large write cache and/or you are recovering to a slow target (e.g. over the 10 Mbps network). If you abort the processing by quitting ZAR, the write cache will be discarded rather than written to the disk. Some files may remain partially copied, and some will be missing. Thus, it is not recommended that you terminate copy process by quitting the program.
