On attempting to copy music from my MBP to Rock on NUC with local USB SSD. Remote OSX file copy returns error code 36.
Bizarrely some of the files were copied to this folder but not all. So not files 09/10/11 UNLESS they are copied into root - that is not to the folder music
See file 09 present tense.wav successfully copied to root. But I cannot drag this into folder music as the operation returns error code - 36
Below a screenshot of the SSD
Any ideas?
