I have a my book 6tb formatted with NTFS hooked to my lynksys router. while tryiong to move files from one folder to the other i get the error included on the screen shot. I have tried unsucessfully to change permissions on the folders. PLEASE HELP!!! I cannot figure this out. I have googled for DAYSSSSSS tying to get this!!!

Hi shmodaddy,

Please connect the drive directly to a computer and see if you are able to make the changes.
Most likely, you would need to contact Lynksys support, since the permissions of the files are controlled by Unix user/root, i.e your router.
