I think you need to move the files that start with BSC, SBSCSubsytem and MCBTSSubSystem into separate directories.

1. Create the separate directories for BSD, SBSCSubsystem and MCBTSSubsytem under the directory you want to search or at nay other path 
chdir("test") ## For eg:test can be directory where the files exist. 
unless (-d "BSD"){
    mkdir("BSD") or warn ("unable to create directory BSD");
}
unless (-d "SBSCSubsystem"){
    mkdir("SBSCSubsystem") or warn ("unable to create directory SBSCSu
+bsystem");
}
unless (-d "MCBTSSubsytem"){
    mkdir("MCBTSSubsytem") or warn ("unable to create directory MCBTSS
+ubsytem");
}

Get the lsit of files that matches the BSD, MCBTSSubsytem etc into separate arrays. 
opendir(DIR, "test")
@files_BSD = grep(/^BSD-\d{14}/, readdir(DIR));
@files_SBSC = grep(/^SBSCSubsystem-\d{14}/, readdir(DIR));
@files_MCBTS = grep(/^MCBTSSubsytem-\d{14}/, readdir(DIR));

Then move the files into respective directories. 
foreach (@files_BSD){
rename($_, "BSD/$_" );
}
foreach (@files_SBSC){
rename($_, "SBSCSubsystem/$_");
}
foreach (@files_MCBTS){
rename($_, "MCBTSSubsytem/$_");
}
