The vutil rebuild file function is accessed on the Rebuild File tab. The rebuild file function recreates or rebuilds the specified indexed file. You should rebuild a file that has become corrupt, or one that contains a large number of deleted or lost records that you want to remove from the file. The vutil rebuild function has many options that allow you to control how the rebuilt file is created.
Note that the -m, -s, and -r options are not available in the graphical interface to vutil. To invoke these options, use the command-line interface to the utility.
