347 zipRemoveExtraInfoBlock - Added by Mathias Svensson
349 Remove extra information block from a extra information data for the local file header or central directory header
351 It is needed to remove ZIP64 extra information blocks when before data is written if using RAW mode.
353 0x0001 is the signature header for the ZIP64 extra information blocks
356 Remove ZIP64 Extra information from a central director extra field data
357 zipRemoveExtraInfoBlock(pCenDirExtraFieldData, &nCenDirExtraFieldDataLen, 0x0001);
359 Remove ZIP64 Extra information from a Local File Header extra field data
360 zipRemoveExtraInfoBlock(pLocalHeaderExtraFieldData, &nLocalHeaderExtraFieldDataLen, 0x0001);
