What does Option #12: Rebuild Index do?

Description:

Solution:
The option #12 utility is useful in fixing projects with interpretation errors
received in SeisDV. Running option #12 takes less time than option #22. Rebuild
interpretation (which does a rebuild index too) and could fix the problem 
without having to do option #22.
 
1.  Make sure you have a current backup of the project before proceeding with
    running option #12, rebuild index files.
 
2.  Check project DSLs for appropriate disk space. Project and Interpretation
    DSLs should NOT be at 100%! Do not proceed with rebuild if this is the
    case.
 
3.  Check project DSLs for appropriate permissions. Should be rw-rw-r on all
    directories and files.
 
4.  Make sure the key files (example vvol_key.dat, .fpb, .idx) that compliment
    the *.disp, *surf, and *.vvol files are located on the same DSL. Otherwise,
    possible corruption could occur.
 
NOTE:Large projects with lots of interpretation could take a long time should
NEVER be aborted while running this option.

PROCEDURE:
 
1.) Option #1 - Initialize access to data area.
    - Enter the project name and password.
    - Select Exploration as Data Area Type.
    
2.) Option #12 - Rebuild Index files.
   *Note: You must enter the path for a temporary directory here. The 
    approximate space required is the total space currently use by the 
    *.fpb, *idx, and *.dat files in the directory containing the IESX 
    *.idx files to be rebuilt.
 
3.) Option #2 - Terminate access to the data area.
 
4.) Option #99 - Exit IESX_Utilities.
