You can use the following advanced options in the Add dialog to automatically select and add all files that satisfy certain criteria:Add only if newerSelect this option to add the specified file to the archive only if the archive does not contain the specified file, or if the archive contains an older version of the specified file. File Roller uses the modification date to determine which file is the most recent. If the version of the file in the archive is the most recent, File Roller does not add the specified file to the archive.If you do not select this option, File Roller adds the file to the archive and overwrites the previous archive contents.If you use File Roller to create backups, the Add only if newer option is very useful. For example, the archive backup.tar.gz contains a week-old backup of your home folder. To update the archive to contain a current backup of your home folder, perform the following steps: Open the backup.tar.gz archive in File Roller.Choose EditAdd to display the Add dialog.Select your home folder in the list box.Select the Add only if newer option.Click Add.File Roller automatically adds to the archive all files that you created during the last week, and updates all files that you modified during the last week. However, File Roller does not remove from the archive the files that you deleted during the last week. The archive update operation is much faster than doing a full backup of your home folder.Include filesType a filename pattern in this text box to include files with names that match the specified pattern.
