Extraction path and options dialog: advanced options
You may specify the following options in this dialog:
Windows file systems keep three different time fields for each file: last modification, creation and last access. By default WinRAR stores only last modification time, but using file time options in Time part of archiving dialog you may enable storing of creation and last access time. Even if a desired time field is present in archive, it is also necessary to set the corresponding time option in the extraction dialog to restore it on extraction. All these options are supported only by RAR archives, ZIP format supports only "Set modification time", for other formats WinRAR always restores only the modification time.
Clear attribute "Archive" on the extracted files. This option is designed for backup purposes.
This option has meaning only for NTFS file system and allows to restore file owner, group, access control and audit information if it was previously saved in the archive. It is necessary to specify "Save file security data" option in Advanced part of archiving dialog to preserve security information when creating an archive. 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 feature is supported only by RAR archives.
This option allows to restore NTFS "Compressed" attribute when extracting files. WinRAR saves "Compressed" file attributes when creating an archive, but does not restore them unless this option is specified.
This feature is supported only by RAR archives.
Usually this mode is most appropriate. WinRAR unpacks contents of archive including the path information into the destination folder.
If the option is set, selected files from the root archive folder and from selected subfolders will be extracted into the destination folder. The path information is ignored.
If archive was created using "Store full paths including the drive letter" mode selected in Files part of archiving dialog and you set "Extract absolute paths" option, WinRAR will create unpacked files in their original folders and disks. Be careful, do not set this option unless you are completely sure that archive does not contain malicious files. You may read more about potential benefits and dangers of "Extract absolute paths" mode in the description of -ep3 switch, which is the command line equivalent of this WinRAR option. This feature is supported only by RAR and ZIP archives.
Do not delete an unpacked archive.
Ask for user confirmation before deleting an unpacked archive.
Delete an unpacked archive without a confirmation.
WinRAR deletes an archive only if it had been unpacked without errors and if all archived files were selected to unpack. If you unpack a multivolume archive, all its volumes will be deleted.
Note that you can save the default state of this option with "Save settings" button in General page of extraction dialog and it will also affect command line and context menu extraction commands. Use "Ask for confirmation" and especially "Always" mode with care. Deleting an unpacked archive can cause data loss if used improperly.
Check the information about creator of RAR archive added by "Put authenticity verification" option in General part of archiving dialog. Turning this option off can save some time when unpacking large RAR archives.
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.
