Unable to delete IDENTIFIER & ATTRIBUTES files.

Win 7 x64 OS.

I did a data recovery to restore hundreds of deleted files on my external hard drive. After some files were successfully restored, I also had hundreds of unwanted "zone.identifier" files and ".attributes" files that I am unable to delete. (See Images A & B) I've tried deleting the zone.identifier and .attributes files but get an "Item Not found" error window, which says "This is no longer located in E:\. Verify the item's location and try again." (See Image C)

I also have a file folder that I am unable to delete. After trying, I get a "The file name you specified is not valid or too long. Specify a different file name." (See Image D) If I try to rename the folder with a valid name, I get the same message. (See Image E)

Any idea how I can delete all these unwanted files?

Rebooting the computer didn't spolve the problem.
