Simplified approach: Store mode in pax extended header, apply best effort on Windows (ignore group/other bits, map owner read/write to deny/allow ACL entries). Detect sparse files on Windows via FSCTL_QUERY_ALLOCATED_RANGES :

Supported via dynamically loaded DLLs (zlib1.dll, libbz2.dll, liblzma.dll) or static linking. 5.1 Alternate Data Streams (ADS) Extended tar format using filename:streamname syntax:
