dictwith command, returncode, output_dir
catalog_recovered_files(output_dir)
Catalogs all recovered files by extension with counts and sizes.
- Returns:
dictwithtotal_files,total_mb,by_extension
hash_recovered_files(output_dir, extensions)
Generates SHA-256 hashes for recovered files, optionally filtered by extension.
- Returns:
list[dict]with file path, sha256, size
sort_recovered_files(output_dir, sorted_dir)
Sorts recovered files into categories: documents, images, databases, archives, executables, email, web, other.
- Returns:
dict[str, int]- category to file count
full_recovery_pipeline(image_path, output_dir, file_types)
