Information
===========

CD-ROM = Compact Disc - Read Only Memory

The files on a CD-ROM are in 'READ-ONLY'-attribute.
This is because you cannot write on a CD-ROM.


Copying
=======

If you want to copy files from your CD-ROM to your harddisk, the
file-attributes of these files will also be copied to your
harddisk.

It all depends with wich copy-program you copy your files.
Some copy-programs don't copy the 'READ-ONLY'-attribute to your
harddisk. (e.g.: 'COPY' ==> DOS, 4-DOS, N-DOS,...)

Norton Commander for example, copies the 'READ-ONLY'-attribute to
your harddisk.  So all these files will be in 'READ-ONLY'-attribute
on your harddisk.  This can cause many problems with some programs,
like files who cannot be read, updated or written to disk.

If you like for example Norton Commander, and you want to copy files
from within N.C., you should use the command 'ATTRIB' after the
copy-process.


The external-command 'ATTRIB' from DOS.
=======================================

With this command it's possible to change the attributes of 1 file or
more, even whole directories with all its sub-dirs and files is possible.

For example you have a directory on your harddisk 'C:\TEST' and all the
files and sub-dirs beneath this directory are in 'READ-ONLY'-attribute.
You can clear these attributes of all these files by typing at the prompt:

  ATTRIB -R C:\TEST /S

Now this program 'TEST' will function properly.
The command 'ATTRIB' must reside in your DOS-path (mostly C:\DOS).
In your autoexec.bat file should be a line like :

  SET PATH=C:\DOS; ...etc.
