 ====== Synousbcopy ======
-''/usr/syno/bin/synousbcopy'' was a script until DSM5. So it was easier to manipulate it respective to replace it inside file system. Further, this script was containing the whole copy button handling. Since DSM6 the copy button acting was moved into an app called “USB-Copy”. Nowadays the script is still there but contains some helper functions probably used by the “USB-Copy” app.
