    SYNOPSIS

           fiz archive[.zoo]
    
    
    

    DESCRIPTION

           Fiz  is  used  to  analyze  damaged  zoo  archives and locate directory
           entries and file data in them.  The current version of fiz is  2.0  and
           it  is meant to be used in conjunction with zoo version 2.0.  Fiz makes
           no assumptions about archive structure.  Instead,  it  simply  searches
           the  entire  subject  archive for tag values that mark the locations of
           directory entries and file data.  In a zoo archive, a  directory  entry
           contains information about a stored file such as its name, whether com-
           pressed or not, and its timestamp.  The file data are the  actual  data
           for  the  archived  file,  and  may be either the original data, or the
           result of compressing the file.
    
           For each directory entry found, fiz prints where in the archive  it  is
           located,  the  directory  path and filename(s) found in it, whether the
           directory entry appears to be corrupted (indicated by  [*CRC  Error*]),
           and  the  value  of  the  pointer to the file data that is found in the
           directory entry.  For each block of file data found in the archive, fiz
           prints where in the archive the block begins.  In the case of an undam-
           aged archive, the pointer to file data found in a directory entry  will
           correspond to where fiz actually locates the data.  Here is some sample
           output from fiz:
    
           ****************
               2526: DIR  [changes] ==>   95
               2587: DATA
           ****************
               3909: DIR  [copyrite] ==> 1478
               3970: DATA
               4769: DATA
           ****************
    
           In such output, DIR indicates where fiz found a directory entry in  the
           archive,  and  DATA indicates where fiz found file data in the archive.
           Filenames located by fiz are enclosed in square brackets, and the nota-
           tion  "==>    95"  indicates  that  the directory entry found by fiz at
           position 2526 has a file data pointer to position  95.   In  actuality,
           fiz found file data at positions 2587, 3970, and 4769.  Since fiz found
           only two directory entries, and each directory entry corresponds to one
           file, one of the file data positions is an artifact.
    
           Once  the locations of directory entries and file data are found, the @
           modifier to zoo's archive list and extract commands can be used and the
           archive  contents selectively listed or extracted, skipping the damaged
           portion.  This is further described in the documentation for zoo(1).
    
           In the above case, commands to try giving to zoo might  be  x@2526,2587
           (extract  beginning  at  position 2526, and get file data from position
           2587),  x@3090,3970  (extract  at  3090,  get  data  from   3970)   and
           x@3909,4769  (extract  at 3909, get data from 4769).  Once a correctly-
           values.   This  occurs  very  rarely, however, and trial and error will
           usually permit all undamaged data to be extracted.
    
    
    

    DIAGNOSTICS

           Fiz always exits with a status code of 0.
    
    
    

    FUTURE DIRECTIONS

           Automation of data recovery  from  a  damaged  archive  is  potentially
           achievable.   However, since damaged archives occur only rarely, fiz as
           it currently stands is unlikely to change much in the near future.
