Converting using dbpower amp

Hiya. I’m trying to convert my iTunes to dsd via dbpower amp on a Mac book pro. now all converted I have a load of lies in applications folder but can’t move them to a separate drive. Anyone know what I need to do please. Thanks. 
Is the drive formatted for Mac? If it's formatted with NTFS, OS X is unable to write to it. 
Hiya. I’m formatting it according to what Apple is suggesting. Is there an instruction video anywhere?
Thanks. Ok look into that
