Most files are stored on a disk in contiguous sectors.  If a file is very large, or the disk is very full, then a file may be stored in many fragments.  This is also very true when a file has been created by added small sections to file, as often happens with logs.

The CnW program will indicate in the log the number of fragments a file has.  By double clicking on the fragment number in the log, details of the fragments will be displayed shwoing the start location, and length of the fragment
