Any program that can...

[Fe2]

Until now, I have been doing this in a text editor:
- backup 'old-file.dat'
- open 'old-file.dat' containing multiple MIDI files
- search for 'MThd' (start of file #)
- delete everything before it (header of 'old-file.dat', if any)
- save (changes, if any)
- search for next 'MThd' (start of file #+1)
- delete everything after it (files #+1, #+2, #+3...)
- save as 'new-file-#.mid'
- close
- open 'old-file.dat'
- search for 'MThd' (start of file #)
- search for next 'MThd' (start of file #+1)
- delete everything before it (file #)
- save
- start over
- restore backup file

That is, slice up a big file containing multiple files into single files.

Is there any program that can do this?

Alright, I found some programs:
