This software contains an option of raw data editing with the "Hex Editor" tool. Inaccurate data modification can lead to irreversible data loss. Please backup your data before making any modifications.
Any fallouts caused by software misuse are your sole responsibility.
NEVER download or install the software to the storage you have lost your information from. This can result into permanent data loss. In case of data loss from a system partition it is strongly recommended to shut down the system and consider using UFS Explorer Emergency Recovery CD.

UFS Explorer Professional Recovery is a full-featured software application designed exclusively for data recovery specialists. The application successfully combines low-level data analysis and editing functions with high-level data recovery tools. UFS Explorer Professional Recovery allows altering original information on the storage as well as provides means for comprehensive data analysis and logical data recovery.

Key software features include:

Immediate access to files and folders

The software provides direct access to intact data on any of the supported file systems without the need of prior scan. As soon as you open the program, it displays all attached storages with accessible file systems where you can find your data. This function is critical for large storages with millions and billions of files when prior storage indexation is unwanted.

Reconstruction of RAID storages

This professional application easily handles standard, nested and custom RAID configurations. The software supports assembly of non-redundant RAID level 0 and JBOD, 1 and 1E mirrors, levels 3 and 4 with dedicated and 5 and 6 with distributed parity. Moreover, nested RAID levels, such as 10, 0+1, 50, 60 etc. are easy to handle using internal program instruments. A special syntax makes possible to set up custom RAID configuration with different data distribution algorithms. Asynchronous data access technique makes further RAID recovery fast and efficient.

Disk-on-disk recovery

The software opens disk image files or virtual disks from a file system already opened in UFS Explorer. With this application you can easily build RAID that stores VMware ESX virtual machines (VMFS file system), open virtual disk directly from VMFS and recover data straight from virtual machine without the need to extract virtual disk first. Disk-on-Disk software feature activates a variety of low-level data access tools such as access to system-locked virtual disks of running Hyper-V server, access to CD/DVD image files stored on a file system of a 'parallel' operating system and so on.

Recovery after file system format

The software analyzes the storage for previous file system formats and allows you to choose among different possible file system configurations for recovery. If you are not sure what file system there was on the storage before format, the software can examine the storage and find all possible file system variants to try all of them.

Support of disk images and virtual disks

UFS Explorer Professional Recovery supports disk images and virtual disks produced by virtual machines of the leading virtualization software vendors including VMware Player, VMware Workstation, VMware ESX Server, VMware Fusion, Microsoft Virtual PC, Microsoft Hyper-V, Parallels Desktop etc. This program operates virtual disks and disk image files exactly in a way as if they were physical disks and allows accessing or recovering lost data from disk images and virtual disks.

Full-disk encryption support

The software works with full-disk encryption providing possibility to access and recover files from encrypted volumes including NAS-storages. Among supported systems are Windows EFS and Linux with its device mapper encryption module (dm-crypt) and LUKS encryption method.

Comprehensive files recovery

A set of tools implemented in the software provides solutions for most possible data loss cases. Depending on the certain situation, the software either simply reads or conducts detailed analysis of file system metadata to find lost files. Even if the metadata is lost permanently, the software can guess file allocation basing on the file system specifics, other files allocations and file content analysis to produce the best possible data recovery result.

Data consistency analysis and error correction

UFS Explorer Professional Recovery is the solution to include tools for low-level data consistency analysis. The software allows identifying location of file/folder descriptor, its contents and mapping of file/folder fragments and navigating among them. If file contents are faulty, it will let you go through file fragments, find the faulty one and correct it. In order to return the file system back into a consistent state the write-enabled hexadecimal editor makes possible to correct minor and moderate file system damages (fix directory entries, move superblocks, fix i-nodes and so on).
