inconsistency

https://en.wikipedia.org/w/index.php?title=ZIP_(file_format)#Local_file_header Compressed size (or 0xffffffff for ZIP64) Uncompressed size (or 0xffffffff for ZIP64)

https://en.wikipedia.org/w/index.php?title=ZIP_(file_format)#Data_descriptor If the archive is in Zip64 format, the compressed and uncompressed size fields are 8 bytes long instead of 4 bytes long (see section 4.3.9.2). The equivalent fields in the local header (or in the Zip64 extended information extra field in the case of archives in Zip64 format) are filled with zero

Should be "are filled with 0xffffffff " for consistency (and to match spec) 72.220.110.71 (talk) 18:12, 2 June 2025 (UTC)
