dir

The dir or direct command displays the list of files in your current directory or account. You can also display the files in other directories by specifying that directory or by using wildcarding:
 
dir dsk2:[10,7]
dir c:\myfiles\*.txt
dir ..\yourfiles\

You can use the wide switch to display the directory in "wide" format (multiple columns). You can also use any other switch supported by your system's dir or ls command.
