How to join .tar.gz splitted files?

  • Hi,

    I have compressed 6 GB folder on our server(LINUX), than splitted using this command,

    tar cf myfolder.tar myfolder
    split -b 500m myfolder.tar myfolder.tar_

    so i got files like this
    and so on.

    After that i downloaded these files in computer(Windows). Now i want to extract them using Power Archiver, Please tell me how i can do this ?

    When i open myfolder.tar.gz_aa in PowerArchiver it is loaded, but when i open 2nd file so i got this error,

    PA can not open this file, It does not appear to be a valid archive.

    Your help will be appreciated thanks.

  • You need to “join” the files back into a single file before it can be uncompressed. L/Unix split seperates on bytes and also has a join command - under windows I guess you could try a utility such as hjsplit.

    Note: you may also have to rename the files by changing the alpha suffic to numeric
    aa -> 01
    ab -> 02
    ac -> 03 etc.

  • @websolpro:

    Still this technique is not working.

    So what did you do and what happened - what error message(s) etc?

    I am already assuming that you have enough disk space and that you have NTFS format (for 6GB file).

  • Hi,

    Thank you, First of all i changed all names .001 , .002 and than used hjsplit and it joined all files, now all are extracting :)

  • :p

  • You can also use the copy command from windows command line:

    copy /b file1+file2+file3 > whole_file.bin

    no extra tools needed :)
