N A directory does not fully exist until a file has been copied into that path. Also, the IPL operates differently from PC operating systems: files stored in and directories created in
the IPL may have the same names.
Example: E
majordirectory/subdirectory/next-level/ CJ}
W majordirectory %2F subdirectory %2F next-level %2F CJ |
Dir•majordirectory/subdirectory/next-level/ ]
In this case, the path is majordirectory/
subdirectory/. The directory that was just
created or changed to is called next-level.
Example: E
custompages/HTMLfiles/ CJ}
W custompages %2F HTMLfiles %2F CJ|This example just created a subdirectory for
storing the user’s custom-made HTML files.

HTMLfiles.
