Advanced scan parameters setting dialog contains a set of data recovery steps and settings as described below.

With Detect file system parameters the software will scan the device for data that allows to ascertain file system type. The check-box is always disabled and is deactivated in case if file system is detected by the program. The task is activated by default together with reconstruct the file system task in case if file system is not detected and file system reconstruction is required.

With Reconstruct the file system task the software will scan the partition for file system metadata and virtually restore the file system. In cases when file system is detected by the software but files and folders seem to be unread or read incorrectly File system reconstruction is recommended. For not-detected file system this task is activated by default. File system reconstruction result appears in File system explorer view tree as Reconstructed file system virtual directory under File system directory.

With Search for deleted files task the software will scan the partition for files metadata and capture deleted, failed or lost metadata for file recovery. This task is offered by the software as a basic operation for cases when file system is detected by the software and you are sure that it wasn't corrupted. Search for deleted files scan result is displayed in UFS Explorer main view tree as Deleted files virtual directory under File system directory.

Detailed (sector-by-sector) scan – the software conducts a detailed scan of each sector of logical disk for file descriptors remaining beyond the metadata area. Additional descriptors can remain on the disk in case of back-up and/or after partition defragmentation.

Note: For the software to start scan operation you may select between Reconstruct the file system and Search for deleted files tasks or activate both.

With Enable IntelliRAW™ scan task the software will search through the partition for files using file extension identifiers. This operation allows to find files even when file allocation information is unavailable. Enable IntelliRAW™ scan task is enabled only if Search for deleted files task is selected and IntelliRAW™ rules count box is filled in. Scan result appears in Detected by type virtual directory under File system directory in File system explorer view tree. The sub-options for this scan type include:

• Assume deleted files are fragmented finds fragments of a file if it was fragmented during recording of files found with Enable IntelliRAW™ scan. With this task the software will detect file fragments, separate them from other files and gather file fragments into one single file.


• IntelliRAW™ rules count box is available for modifications in Advanced scan parameters setting dialogs for all file systems. Add button opens an open file dialog to add rules from a file. You may add own rules by placing rule files to software installation folder or by adding them with “Add” option from a different location. The basic set of predefined rules is available in “intelliraw.urrs” file that is supplied with the software. It's not recommended to modify content of this file or preserve this file before any modification. Clear button will clear the box.
