… that’s because you can put them in there anywhere you want.

Thanks. thats what i suspected. thanks for confirming. two more clarifying question. that 

  1. can i have any level of folders and subfolders (this will help me in organising the files) or is there a restriction
  2. also, there is a folder called network sync. my understanding is that this folder sync the files from my NAS automatically. if i disconnect the WD from network , will these files still be available to play? the reason i am asking is this that if this is the case, i can just sync this folder with NAS and then can take the WD with me on the go and use it in car or a motel without the worry of copying the folders manully
