Who owns the folder that you are trying to write to? And what are the rwx permissions on the folder? I suspect that root owns it. Example.
ls -ld /usr/folder/folder/etc
If root own it then youll need to be root, and the folder will need write perm.
And how are you trying to copy/move the files?
If you need to be root then su to root and copy the files.
#cp /files/to/copy /place/you/want/them
$ means you are user. # means you are root.
