Please, test with a small sample of your given directory.

It creates a file.bk from the file that it finds in the directory, for safety reasons. If the result in the file.bk is correct, remove the
last commented command to rename the backup to the original name and run in the production/real directory

Run as:
Code:
perl kylle345_run.pl /path/to/directory/*.txt

Code:
#!/usr/bin/perl
# kylle345_run.pl

use strict;
use warnings;
use File::Copy qw(move);

# process each file given at the command line
for my $fname (@ARGV){
    my $fh;
    # open the current file    
    if(not open $fh, '<', $fname){
        # file could not be read; skip
        print STDERR "$fname could not be processed\n";
        next;
    }
    print "Processing file: $fname ...\n";

    # obtain substrings from file name if not skip
    my @names = $fname =~ /\[(.+?)\]\[\w\]/g or next;
    open my $fh_bk, '>', "$fname.bk" or next;
    my $before_last = "AMEL\tX\tY\t\tX\tX\n";

    # read the current file
    while(<$fh>){
         # only at second line substitute the xxx.fsa with parts of filename
         s/\w{3}\.fsa(\s+)\w{3}\.fsa/$names[0]$1$names[1]/ if $. == 2;
         # add a line before last
         if(eof) {
             print $fh_bk "$before_last$_";
             next;
         }
         # write to a copy ending in .bk
         print $fh_bk $_;
    }
    close $fh;
    close $fh_bk;
    # test first and if it does correctly, remove the
    # # from next line to rename backup to original name
    #move "$fname.bk", $fname;
}
