CSM Tech Publishing has been operating for six months, and business is good. You do a spot check on server resources and find that RAM use is at 50%, which is fine, but the data volume on the server used by employees to store and share documents is approaching 90% full. There are two volumes on this server: one for OS and program files and one for data storage. You inspect the data volume and find that some users are storing large amounts of data on the server. You check with the owner and determine that each user should require only about 4 GB of storage on the server for necessary documents. Because some users are clearly exceeding this limit, you're asked to come up with a solution. What file system option can you use, and which file system format must be used with this option?
