3 corrupt password protected Ultra LZMA files

  • Tried the fix in http://sourceforge.net/p/sevenzip/discussion/45798/thread/e34b4a1d/?page=0, still no access to the recovered archive, unsure if the fact they are password protected is significant. Error, can not open as archive. Tried with and without password at each split.

    Any chance of recovery here?

    I need hex for start of file and end of file in such format:

    for first 32 bytes:
    offset of main header = 32 + (little endian) 07 5A 50 F8 60 C9 0E 07 01
    size of main header is: 6D 00 00 00 00 00 00 00
    but size of file is another.

    Probably the end of file and start of file are not from same archive.

    What error do you have for that file?

     
  • When extracting? 'data error in encrypted file 'file', wrong password? on 10464 files

     
  • Also I know the password is ok, as the extract has extracted .exe files ok. These can be run. Folders and files have extracted in correct structure, but all files are 0KB

    If you update archive, it's possible to get archive that use different passwords for different files.

    Show the list of files
    7z l a.7z > list.txt
    and
    7z t a.7z -pYourPasswordHere > test.txt
