Pre-Recovery Preview
The preview is an essential feature of all Hetman recovery tools. Pre-recovery preview allows peeking inside deleted files before you decide whether it’s worth recovering. The preview supports hundreds of file formats including all popular document and image formats, a bunch of video formats, compressed archives, backups, emails, text and HTML data. You can even preview information about executable files or use the built-in HEX editor for low-level access. Finally, for every recoverable file you can see its exact physical location on the disk.

The Engine
Hetman Uneraser may look simple, but it features a highly sophisticated data recovery engine under the hood. In fact, it shares the recovery engine with the much more expensive, professional tool Hetman Partition Recovery. There are two approaches to the recovery: Quick and Comprehensive. In Quick mode, Hetman Uneraser will scan the data in the FAT or NTFS file system, returning the list of recently deleted files in a few brief moments. This mode is blazing fast, really, but it can miss certain data, especially if a file was deleted a long time ago. In addition, the Quick mode won’t be much use if you formatted the disk (or flash drive, or memory card) as the file system will be empty after formatting.
To help you recover information in complex scenarios, Hetman Uneraser employs the highly sophisticated Comprehensive analysis mode. In this mode, the tool reads the entire disk surface and uses a number of heuristic, content-aware analysis techniques to detect known file formats by their characteristic signatures, calculate their exact physical location and finally recover from the disk. This mode may take quite some time depending on the size of your disk and the amount of information stored on it, but it is able to recover documents, pictures, databases, archives, emails and many other types of data a long time after they’ve been deleted.

Data Safety
Safety was a major goal when Hetman Uneraser was designed. The tool uses strict read-only access to storage media being analyzed. This approach ensures it won’t damage anything it’s up to recover. Make sure you don’t write anything onto the disk being recovered yourself. For example, make sure that you download, save and install Hetman Uneraser onto a disk or partition different from that you’re about to recover. The ultimate safety can be achieved by using virtual disk images. This technique allows capturing a bit-precise image of the volume you’re about to recover in a single sweep, effectively minimizing the number of disk access operations and reducing the chance of accidental failure of a damaged device. The disk image can then be used to recover the files.

Saving the Files
In order to ensure the safety of your data, you’ll want to use a different disk or drive letter to save files being recovered. Sounds simple, but only if you have enough disk space available. If you don’t, Hetman Uneraser offers a convenient wizard allowing you to choose whether you’ll be saving the files onto a hard drive, burning a bunch of CD’s or uploading them to a remote server.
Supported storage options include the ability to choose any local or remote disk, burn a CD/DVD with a built-in disc burner, or upload the files to a remote location over the FTP protocol. You’ll have the option of saving everything into a single folder or re-creating the original folder structure.
System Requirements and Compatibility
Hetman Uneraser works with all versions and revisions of FAT and NTFS, including VFAT, FAT 12 / 16 / 32 as well as NTFS 3, 4, 5. It can correctly recover information from compressed and encrypted volumes as well as all crypto containers (as long as you know the original password). Hetman Uneraser is compatible with all 32-bit and 64-bit versions of Windows including Windows XP, 2003 and 2008 Server, Vista, Windows 7, Windows 8 and Windows 10.
