C:> cd c:\this is a god-awful directory or you could type C:> cd c:\this*.
Win9x can create directory names / file names with spaces but then they have to enclose the name in quotes to keep the space from terminating the command. This discourages using the command-line in Win9x. Spaces are OK in NT at command-line:
C:> type c:\data\this file rather than C:> type c:\data\"this file" This makes the dark place a little friendlier in NT.
But like all tools you have to be careful. Particularly if there are subdirectories with names matching the portions of a folder with a long file name. Experiment with the copy, del, and rd commands in a subfolder with folders named quickbooks and "copy of quickbooks". If there is ambiguity, use quotes or the Explorer GUI.
