For a split or spanned Zip file, use the following command instead: "C:\Program Files\WinZip\wzzip" -yfs zipfile.zip WZZIP will create a new Zip file with a FIXED suffix in the file name. The original Zip file will not be modified. Only the data in the original Zip file is used. The FIXED Zip file is structurally sound but the data may still be corrupt. WZZIP does not fix the zipped data itself. If the zipped data has a CRC error or the zipped data is corrupt, then the resulting fixed Zip file will still be corrupt.

alpha or beta version. If new version also doesn't help, read this manual. Required software: 7-Zip (latest version, that can be stable, alpha or beta version). Some program with hex viewer or editor, for example, FAR Manager. 7z archive structure 7z archive consists of 4 main blocks of data: Start Header (32 bytes): it contains signature and link to End Header Compressed Data of files Compressed Metadata Block for files: it contains links to Compressed Data, information about compression methods, CRC, file names, sizes, timestamps and so on. End Header: it contains link to Compressed Metadata Block. Note: If 7z archive contains only one file without encryption, 7-Zip stores Metadata for that file in End Header in uncompressed form, and there are only 3 main blocks in that case. Archive example Archive example: a.7z (3740 bytes) that contains 5 files compressed with LZMA method. Start of archive: 0000000000: 37 7A BC AF 27 1C 00 04 5B 38 BE F9 59 0E 00 00 0000000010: 00 00 00 00 23 00 00 00 00 00 00 00 7A 63 68 FD 0000000020: 00 21 16 89 6C 71 3D AB 7D 89 E6 3C 2E BE 60 24 00: 6 bytes: 37 7A BC AF 27 1C - Signature 06: 2 bytes: 00 04 - Format version 08: 4 bytes: 5B 38 BE F9 - CRC of the following 12 bytes 0C: 8 bytes: 59 0E 00 00 00 00 00 00 - relative offset of End Header 14: 8 bytes: 23 00 00 00 00 00 00 00 - the length of End Header 1C: 4 bytes: 7A 63 68 FD - CRC of the End Header Relative offset of End Header is relative from the end of Start Header, that is at offset 0x20 (32 in decimal). Real offset of End Header in example archive = 0x20 + 0x0E59 = 0x0E79 20: 00 21 16 89 ... - start of compressed data. Note: if the file was compressed with LZMA method, the first byte is always 00. If first byte is not 00, then archive uses another method (it can be LZMA2 or encrypted data with AES). End of archive: End Header (offset = 0x0E59, length = 0x23): 0000000E70: 17 06 8D AD 01 09 80 0000000E80: AC 00 07 0B 01 00 01 23 03 01 01 05 5D 00 10 00 0000000E90: 00 0C 81 1A 0A 01 3C 70 52 F7 00 00 Possible values for first byte in End Header: 17 - End Header contains the link to Metadata Block. 01 - Metadata block is stored in End Header. Corruption types There are some possible cases when archive is corrupted: You can open archive and you can see the list of files, but when you press Extract or Test command, there are some errors: Data Error or CRC Error. When you open archive, you get message "Can not open file 'a.7z' as archive" Corruption case: Data errors or CRC errors
