![]() ![]() Also it's typically such files that have an EXIF section as part of their file design. None of the generic file recovery tools I know of use EXIF data BTW unless they're dedicated raw scanners: For dedicated raw scanners, often geared towards media files such as photos and videos, it's the only way to extract more specific data about the detected files. And, if they detect this they keep result of file system scan and remove result of the raw scan eliminating a duplicate. ![]() Now my stance is that a good tool, if it is able to virtually reconstruct the file system, and good tools often are unlike less good tools, makes it unnecessary to recover results of the raw scan.Īlso, many good tools, I'll mention ReclaiMe and R-Studio, have a mechanism in place that recognizes files that are recovered both by the file system scan and the raw scan. Problem with the files with automatically generated filenames is that they are so hard to identify without opening and viewing them.Īlso, often people tend to recover everything, better be safe than sorry. So these will result in more automatically generated filenames. In addition to this several copies of a file may exist even if it only occurs once in the file system, let's call them 'stale files', and these are typically picked up by the raw scanner. ![]() If file system structures are largely intact and actual file contents have not been overwritten potentially each recoverable file is detected twice as many tools use both methods. The software may assume it detected the start of a JPEG file is these bytes are detected at a cluster boundary, however it has no way of knowing additional attributes such as the filename so a generic name is auto generated. For example, all JPEG files start with byte pair FF D8. Raw scan: Detect files based on signature. Using the data it is possible to virtually reconstruct the folder structure complete with filenames and attributes. Basically file recovery software has two main strategies to recover files:įile system based: The tool scans the drive for file system structures that point to files. I would like to suggest using better software to recover the files with in the first place. This is not a direct answer but it may be helpful none the less. ![]()
