Archive name and parameters dialog: advanced options

Save file security data

This option has meaning only for NTFS file system and allows to save file owner, group, access control and audit information. You need to have necessary privileges in order to use this facility. Processing of security data may decrease the speed of archiving operation, so set this option only if you understand its meaning and really need it, in most cases security processing is not required for home users.

This option is supported only for RAR archives.

Save file streams

This option has meaning only for NTFS file system and allows to save alternative data streams associated with a file. It is especially important under Windows 2000 and XP, which use streams to keep some file dependent information such as file descriptions. If you use WinRAR to backup your NTFS disks, it is recommended to enable this option.

This option is supported only for RAR archives.

Pause after each volume

By default WinRAR asks for confirmation before creating or unpacking next volume only for removable drives. This option forces WinRAR to ask such confirmation always. It can be useful if disk space is limited and you wish to copy each volume to another media immediately after creation.

Old style volume names

By default RAR volumes have names like 'volname.partNNN.rar', where NNN is the volume number. Using this option switch it is possible to switch to another, extension based naming scheme, where the first volume file in a multi-volume set has the extension .rar, following volumes are numbered from .r00 to .r99. It may have sense, if you are going to unpack an archive under the plain MS DOS, which does not allow more than one dot in a file name.

Recovery volumes

This option is available only when you create a multivolume archive, in this case you just need to select the number of recovery volumes to create. You may also append a percent character to this parameter, in such case the number of creating .rev files will be equal to this percent taken from the total number of RAR volumes. Each recovery volume allows to reconstruct one missing volume file. You may read more about this feature here.

Background archiving

Minimize WinRAR to tray when starting the archiving process.

Turn PC off when done

Turn PC off after completing an operation. The hardware must support the power off feature.

Wait if other WinRAR copies are active

Wait if other WinRAR copies are creating, modifying or unpacking an archive and start the operation only when other WinRAR tasks are complete. If you are going to perform several archiving or decompressing tasks, such queued execution can help to reduce amount of disk seeks and improve overall performance.

Recovery record

Set a size of the recovery record in percent to the total archive size. The maximum allowed value is 10%. Larger recovery record allows to recover from more serious damages, but at the same time it increases archive size, so 1 - 3% is probably optimal. This input field is available only if you enabled " Put recovery record" option in the General options of this dialog.


Opens Advanced compression parameters dialog, where you may configure different modules of WinRAR compression algorithm. Improper settings in this dialog may seriously hurt archiver performance, so use it carefully.

SFX options

Selects a self-extracting module and sets a number of optional SFX parameters like a destination folder or window title. Note that SFX parameters are applicable only to Windows GUI module and are not supported by console or non-Windows SFX. The "SFX options" button is available only if you enabled "Create SFX archive" option in the General options of this dialog.

It is possible to store selected SFX options in a compression profile, WinRAR puts commands describing SFX parameters to the archive comment.

Set password

Set a password to encrypt archived files. It is valid only during a single archiving operation and overrides the default password entered in File menu. If the default password is present, it will be restored after the archiving operation is completed. If the default password was absent before starting archiving, it also will be absent after finishing the operation.
