A Linux system user has configured the document folder structure for her department. She has found that she sometimes needs the same file such as policy and procedure manuals to be located in multiple folders. She also wants to be sure that if the file is modified, the modification is available in all folders. What do you suggest?
A) use the Shadow Copies feature to monitor for changes
B) tell her to manually copy the file at the end of each day
C) write a script to copy the file to all folders periodically
D) use hard links to make the file appear in several folders

Hard links allow a single file to appear in multiple locations in the filesystem. Any changes made to the file are reflected across all links, as they all point to the same inode on the disk. This is the most efficient way to meet the requirement of having the same file accessible from multiple folders with all changes being synchronized.
