Filesystem analysis
Directory and file view
The filesystem content view is split into left and right sides.
The left side shows the directory tree, and the right shows files in the selected directory.
The files are color-coded according to the validation result (see below).
You can mark specific files and directories for copying.
Scan control
The progress screen shows the number of files and directories discovered so far.
You can "Pause" the scan before it is complete to look at what the scan has found.
The "Pause" command is unavailable for FAT16, FAT32, and exFAT filesystems.
This is because of the algorithm limitations.
Validation
When the scan is complete or when you pause the scan,
Klennet Recovery starts examining file contents to determine if the contents are valid.
You do not need to wait for validation to complete before copying the files.
Important: The validation results are not precise. This is because
- validation may miss some damage because it does not check every byte in every file;
- validation only covers a limited set of file formats;
- some files may have extensions mismatched to the file format (for example, a PNG file with a JPEG extension).
Understanding validation statistics
The filesystem analysis window shows the aggregate validation statistics in the toolbar. There are two aggregate metrics:
The first one tells you how many (or what percentage) of files check out good (of all the known file types).
A higher percentage indicates better recovery quality.
The second metric tells you how many files are of the known formats.
The toolbar again shows you the number of files and the percentage.
A higher percentage indicates better reliability of the first metric.
Aggregate validation results.
The first line indicates how good the recovery quality is.
The second line indicates how reliable the first line indication is.
Individual file validation cues
The file list displays files in color according to the validation status:
- gray - not yet evaluated;
- black - unsupported file format;
- green - valid file;
- red - damaged file;
- magenta - on BTRFS, the chunk entry corresponding to the file data is missing.
Selecting and deselecting files
You can select files to copy by checking the appropriate checkboxes on anything from top-level
filesystem directories down to individual file versions.
You can also select multiple files matching some criteria using the Mark button on the toolbar.
Selection criteria include file name, minimum and maximum file size, and file version (where versions are available).
Selecting and copying multiple versions of files
On some of the supported filesystems, Klennet Recovery can recover multiple versions of the same file.
If you select everything by checking the top-level filesystem directory, all the versions will be selected and copied.
The same applies if you use Copy - All button on the toolbar.
The latest (most recent) version has the regular file name (filename.dat),
and the previous versions are numbered (filename (1).dat), with older versions having higher numbers.
To select only the latest versions of the files, use the Mark button on the toolbar
and set File versions to Select the latest version.
This will select the latest versions where several versions are available.
File name lists
You can export the file list in CSV format, import it into your favorite spreadsheet tool, and look through it. Furthermore, you can remove some lines from the file and then import the file back. This will select or deselect the files remaining in the file. The intended use of this feature is to facilitate file selection in complex situations. You can only import the file you exported in the same recovery window.
Copying files
Use the corresponding toolbar button to copy all files or just the selected files.
You will need to enter the target path.
If you need to recover files to a network share, please look at this page.
If there are two recovered files with the same name
or if the target directory is not empty, the new files are renamed.
