cant copy music

I cant copy music music from my pc to my unit. It worked before and now, everytime i transfer songs to my unit, a message of "cannot copy such song. The directory or file cannot be created. Pls help.

maybe you reached the fat limitation. WIth fat16 it has a limitation of like 150 files in the root directory. If you create folders and drap and drop it in their, or save your files and format it as fat32 should fix your issues. Good luck

when you say “format it as fat32” do you mean the Micro SD card?
