I was wondering, since executing unrar -x file.part01.rar 123.zip destinationPath would automatically iterate through the list until the file 123.zip is found, is there a way to stop that auto search for multivolume archives?

For example, I have a set of 100parts of a multipart volume, it would take some time to find the file if the file were to be located at part51. Instead, I would like to generate two processes that starts at part1 and the other starts at part50. If I were to execute unrar -x file.part50.rar 123.zip destinationPath, it skips part50 and starts over to the top.

Second option, if possible, is there a way I can just execute unrar -x file.part50.rar 123.zip destinationPath and if file is not found exit/stop process and start a new command execution unrar -x file.part51.rar 123.zip destinationPath.

Any suggestions or advice would be very much appreciated. Thank you.

Do not use the solid archive type, when creating the archives:

A solid archive is a RAR archive packed by a special compression method, which treats all files, within the archive, as one continuous data stream.

(...)

But it also has a few important disadvantages:

  • slower updating of existing solid archives
  • to extract a single file from a solid archive all preceding files must be analyzed. This makes extraction from the middle of a solid archive slower than extraction from a normal archive, but, if all files are to be extracted from a solid archive, the extraction speed will not be affected.

  • Thank you for the response, Michael. I believe there is really no workaround to it if I wanted to skim through a solid archive type. I just wanted to make the search quicker for my current project and the multipart is mandatory for this since those volumes are not mine and I cannot modify their process. If anyone has any suggestions, that would be great. But as it stands, looks like I would have to stick with the current solution. Starting at the top. Oct 4, 2021 at 22:28
