Tar Utility For Windows -
On extraction, recreate ADS via CreateFile with filename:streamname . POSIX mode → NTFS conversion:
// Windows-specific mode mapping header.mode[0] = '0'; header.mode[1] = info.isReadOnly ? '4' : '6'; strcpy(header.magic, "ustar");
// Pipeline: TarWriter -> GzipFilter -> FileWriter tar utility for windows
// Write file content if (!info.isDirectory) HANDLE h = CreateFileW(path.c_str(), GENERIC_READ, ...); WriteFileContent(h, info.size);
:: List contents of a .tar.xz file tar -tf software.tar.xz // Pipeline: TarWriter ->
// Write header block WriteBlock(&header, 512); padToEvenBlock = false;
return true;
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 :
