The Defragment function in the Disk Utilities menu can
list any fragmented files or directories that may reside on
a disk, and can either repair or pack the files.

As files are created on, written to, or deleted from disk
storage, the system is constantly allocating or freeing up
blocks of data. As more and more files are placed on a
disk, the size and quantity of contiguous blocks for data
diminishes.
Eventually, a point is reached where a file is too large to
be stored as one contiguous block of data, and is instead
fragmented into several pieces, each one stored in a dif-
ferent location on the disk. As more and more files are
added, fragmentation becomes worse, because the maxi-
mum size of a contiguous block continues to diminish.
The disk drive(s) and file system are capable of keeping
track of fragments. However, the drawback to having a
fragmented file is it takes longer to read the file from
disk, since the drive heads have to physically travel to
several different locations to read a single file. This
results in longer read times.
The best way to eliminate fragmented files is to move
everything from the disk containing the fragmented files
onto a different disk, format the original disk, then return
the files to the original disk as one large block of data.
Obviously, this method is only practical if the backup
disk is fast; i.e., another hard disk, or a cartridge drive.
