Why .RAR file contains different files with the same name

I have a .RAR file containing different files with the same name.

For instance,

index.txt 40 Text Document 04/01/2010 4:40PM
index.txt 22 Text Document 04/01/2010 4:42PM
index.txt 10 Text Document 04/01/2010 4:45PM
index.txt 13 Text Document 04/01/2010 4:50PM

Why?

As before, files can be in different ways, but, as I will show later, this is not always the case.

If you use WinRAR to display the contents of a file, and your parameters are set as follows, then only you have files with the same name, but they are in different paths.

  • Options → File List → View flat folders (ctrl + h)
  • Options → File List → Details

After the CRC32 column, there is one called Path. If this is not the case, extraction should not be a problem if:

  • Extract → Extract path and parameters → Advanced → Extract relative paths.

-ver[n] File version control

        Forces RAR to keep previous file versions when updating
        files in the already existing archive. Old versions are
        renamed to 'filename;n', where 'n' is the version number.

        By default, when unpacking an archive without the switch
        -ver, RAR extracts only the last added file version, the name
        of which does not include a numeric suffix. But if you specify
        a file name exactly, including a version, it will be also
        unpacked. For example, 'rar x arcname' will unpack only
        last versions, when 'rar x arcname file.txt;5' will unpack
        'file.txt;5', if it is present in the archive.

        If you specify -ver switch without a parameter when unpacking,
        RAR will extract all versions of all files that match
        the entered file mask. In this case a version number is
        not removed from unpacked file names. You may also extract
        a concrete file version specifying its number as -ver parameter.
        It will tell RAR to unpack only this version and remove
        a version number from file names. For example,
        'rar x -ver5 arcname' will unpack only 5th file versions.

        If you specify 'n' parameter when archiving, it will limit
        the maximum number of file versions stored in the archive.
        Old file versions exceeding this threshold will be removed.
