Permission denied in accessing file system in Linux/Unix

Have you ever experienced this message "Permission denied" when trying to access a file system in Unix/linux.


I have created lower level user eg: noci and I have given full permission to read the folder structure

eg :
drwxr-xr-- 11 root root 4096 Aug  4 13:23 Folder

folder owner is root, but i have given read access to all as you can see.

But when tried to access folder it gives me " Permission denied"  message.


Solution:
Give the execution permission. Without execution permission user cannot go inside folder structure.
