yes it is a multipart file. But the archive is not extracted to the given directory because of this error.

Also can you tell me how to process each extracted file one at a time such that one file is extracted and its contents are processed for a regex than the next one is processed in similar fashion and so on instead of just extracting in a single go?

When you have a multipart file i.e

test.part1.rar
test.part2.rar
test.part3.rar
[download]

all parts form a chain.

what it does is that when reading the first part test.part1.rar,it extracts all the file contents spanning all other parts but also scans the filenames for the rest of the parts so that in a batch job they do not get needelsy processed again since they have been already extracted;that is the caching process.

The "error" you see simply means that it has already seen the other parts and so diregards their processing. That is not the cause of the file not being extracted. Post your code to check what you are trying to do

unfortunatelly this cannot happen;everything has to uncompressed in one go

My code is same as i have shown earlier

use Archive::Unrar qw(list_files_in_archive %donotprocess process_file
+);    
use IO::CaptureOutput qw(capture);
 
my @files;

{     
local ($stdout, $stderr);  
capture sub {list_files_in_archive(  file=>"C:/perl2exe/For perl 5.10.
+1/test.rar" ,undef)}, \$stdout, \$stderr;

@files=map {/Archive contents : (.*)/ } split ("\n",$stdout); 

}

foreach (@files) {
    print "file ",++$i," : ",$_,"\n";
}



($result,$directory) = process_file( 
                            file=>'C:/perl2exe/For perl 5.10.1/test.ra
+r', 
                            password=>undef,
                            output_dir_path=>"C:/extract/",
                            
                                      );

                                      
                                      
}                                      
print "$result";                                  
print "$directory";

$result gives me the chain error
