When we delete files from our computer or device, they are not completely lost until their memory locations are deleted during a device wipe. Many of their fragments still remain in unallocated memory and can be reconstructed theoretically.
What is File Carving?
File Carving is a process of reconstructing computer files which might have been formatted or effectively deleted by the user. The software has to accurately collect pieces from a large data pool present in the hard disk or other storages, even without helpful metadata indicators or other specific guidance.
File Carving tools use various markers like headers and footers and try to identify parts of a file. This software relies on heuristics and probability handling tools to successfully collect required files. Beyond this, advanced algorithms help to improve the file recovery results.
Though File Carving is largely based on guesswork, if we use the right tool with advanced features and capabilities, the file recovery outcomes will significantly improve and help bring order out of the chaos.
