Hidden File

Any file that is on the disk but has a special flag set in the directory
that "hides" it from normal view. The system files are usually hidden files. 
You won't see hidden files listed if you do a DIR command. To list and 
manipulate hidden files usually requires the use of a separately purchased 
program. 

The other attributes (characteristics, properties) that DOS keeps track of for
each file are described in the DIRECTORY definition.
