permission denied while copying eventhough necessary permission exist

Question

I have a file(file) with permission 500. In Linux, I tried to copy (using cp) that file into a folder (a) whose permission is 600. Even though folder have write permission, I am getting " cannot stat `a/file': Permission denied error.

Could anyone explain why is it so?

Answer 1

Is it because directory does not have executable permission ? Execute bit allows the affected user to enter the directory, and access files and directories inside.
