    Hi,

    I m on window 7
    I have split a files and choose 700Mo. Picture inside

    I have four files :

    05.7z.001
    05.7z.002
    05.7z.003
    05.7z.004

    After I have send to a web serveur and delete picture on my computer.
    It was one month ago.

    Yesterday I download all files. I choose the first file and extract. Thats works, I have now one file : 05.7z
    I try to extract this file but I have this message : Can't open file as archive

    And Today I see all volumes have not same size.

    05.7z.001 : 343Mo   
    05.7z.002 : 700Mo
    05.7z.003 : 700Mo
    05.7z.004 : 102Mo

    upload on the serveur was interromped I think.

    How can I recupered the rest of the pictures ?

    Thank you

    You must restore original size of 05.7z.001 file - 700 MB. Just add any data to the end of that file.
    You can do it with rename / split / combine commands of 7-Zip File Manager.

    When 05.7z.001 will be 700 MB, you can try to open that archive.

    Hi thanks for your answer.

    I understand I must add any data in 05.7z.001 with files but I don't understand  how i must do it

    I must make an archive size 357 Mo per exemple and add this to the end of 05.7z.001 but I don' t understand the way.

    1) Run 7-zip file manager
    2) look exact sizes in bytes or 05.7z.001 file  -> size1
    3) select 05.7z.002 file and call "split" command. In split size field, write two strings with space:
    size1 1000M
    it will create 05.7z.002.002 with correct size (something about 357 MB).

    4)
    copy file 05.7z.001  to a.001
    copy file 05.7z.002.002  to a.002
    select a.001 file and call "Combine" command. it will create a file with correct size (700 MB)
    5) Rename "a" file to 05.7z.001.
    6) Try to open 05.7z.001.

    Thank you very much.

    I have "combine" with 7z because it was no possible to extract. Freeze and 184 files errors.

    I have extract with winrar. but it's so bad. Just extract jpeg low quality and I can't extract raw files and all raw files (184) are corrupted
    So, in 05.7z.001, they are informations about pictures are in other file part ?

    7-zip uses solid compression.
    Open archive in 7-Zip and call "Info" command.
    "Blocks" property shows the number of blocks.
    If the number of blocks is "1", then all data after corrupted part can not be restored.
