Rikuperimi i Skedarëve të Fshirë

File carving is the technique of reconstructing files directly from raw disk sectors, ignoring file-system metadata.

When a file is deleted on most file systems, the data blocks are marked as free but not immediately overwritten. A simple delete followed by imaging the disk is enough to recover a lot of content — scalpel, foremost and photorec all scan the image for file signatures (magic bytes) at the start of each cluster and reconstruct files whose sectors are still sequentially stored. Modern file systems and SSDs with TRIM make this harder because the drive actively erases freed blocks. Fragmented files are harder because the carver does not know the order of clusters. Advanced carvers like bulk_extractor perform entropy analysis and reconstruct JPEGs and PDFs even with mild fragmentation. For databases and virtual machine disk images embedded inside a larger image, nested carving may be needed to pull out individual records. In practice, full carving of a modern 1 TB drive can take hours and produce gigabytes of false positives. Experienced analysts carve selectively — targeting a specific file type, a particular time range, or a cluster of unallocated space near a known indicator of compromise — rather than carving the entire image. It is a slow, careful process that often yields the decisive artifact in an investigation.
