Here you may specify some additional archiving options.
If high archiving speed is more important for you than compression ratio, enable "Faster, but less tight compression".
If you wish to delete files after they had been successfully archived, set "Delete files after archiving".
If you need to create a self-extracting archive, enable "Create self-extracting (.exe) archive" option. Such archive does not need WinRAR to be unpacked, it has exe extension and it is enough to run it (double click on its icon) to unpack its contents.
You can press "Set password�" button and specify a password if you wish to encrypt archiving files. Do not forget your password, it is impossible to unpack encrypted files without it.
Also, if you create a new archive, you may split it to several separate parts (called volumes). Sometimes it may be more convenient to have several files of smaller size than one large file. If you wish to do it, just enter a size of single part in the input field near the bottom of dialog. You can specify the size in bytes, kilobytes, megabytes or gigabytes. Just select an appropriate item in drop down list to the right of volume size field. Decimal fractions are allowed.
If you update an already existing archive, options to create self-extracting archive and to split it to parts are disabled. They are accessible only in case of new archive.
Note that all settings in this dialog are optional, usually you may keep their default values.
When done, press "Finish" button at the bottom of dialog to start the archiving operation.
