Question : cp command wont copy iso image contents to hard drive

I mounted an iso to my hard drive but when I tried to copy the contents from the terminal not all the files would transfer.  

I entered cp /dir/filename ./

The bigger files were omitted and when I looked at the files in gnome file browser the files that had copied had locks on them.

Any Ideas??
