Updating split archives

    I cannot seem to create an update archive using a base archive that is split. The same update commands work if the base archive was not split, but when it is, the new update archive contains all the files of the original archive.

    Create base archive files.7z with all files in c:\files
    7z a c:\temp\files c:\files -v10m

    Create update archive filesupdates.7z with changes to c:\files folder
    7z u c:\temp\files -u- -up0q3x2z0!c:\temp\filesupdates c:\files -v10m

    This does not work. If you remove the -v parameter (thus not using split archives) the command works fine.

    Is this a bug or simply not supported? I need this because I am doing backups to Google Drive and need smaller chunks to upload (and there's a max file size) so that they all eventually get sent to the cloud.

    That feature is not implemented.

    Thanks Igor. Hopefully it's something that can be implemented in the future.
