I am using Family Tree Maker for Genealogy. When I try to back it up
to a CD the file always is Read Only. The same with anything else
that I want to put on a CD. How do I change the Read Only
attributes? I go through the procedure, but the next time it always
reverts back to Read Only. The Read Only files give me a message that
they are Read Only and new information will not be saved. I've also
gotten messages such as "you do not have permission to open this
file" when I am trying to save something to the CD. What am I doing
wrong or how can I use these read only files should it become
necessary.
CD-ROM = Compact Disc - Read Only Media
Read Only! And it means it! Any file you put on a CD is read-only.
Any file you copy off of a CD will have the read-only file attribute set
and you will have to clear it. If you want the application (which
apparently does not support writing to CD media) to write to a CD-R[W]
then save to different filenames, or delete the same-named file before
writing a new same-named file. Note that deleting a file from a CD does
not physically removed it. The TOC (table of contents) on the CD gets
updated to remove the reference to that delete-marked copy (you can
erase a CD-RW but you can only delete-mark files on CD-R).
Alternatively, have your application write to the hard drive and you can
later archive it (i.e., copy it) onto the CD-R[W].
If you get a UDF (Univeral Data Format) packet writer utility then you
can make the CD-RW (must be rewritable) act like a big removable floppy.
Ahead's Nero has its InCD utility and Roxio's Easy CD Creator has its
DirectCD utility. These are installable file systems (so you'll need to
reboot after installing them) which means they load on Windows startup
to provide another file system. CDFS is an installable file system,
too, and what you are already using to use CDs. There are problems with
UDF'ed CD-RWs. They may use a different scheme than what a UDR reader
can use so you may find some systems on which a UDF reader has been
installed that cannot read your UDF'ed CDs. Everytime you insert a
blank CD-RW, the UDF writer will attempt to format it using UDF (you may
get prompted, you may not, it depends on the utility and options). You
will probably incur BSODs (blue screens of death) more often since the
UDF writer loads at the kernel privilege level as an installable file
system, and my experience with UDF writers is that their authors haven't
quite perfected their software to be stable (but I haven't retested InCD
and DirectCD for about 2 years now). If you take your UDF'ed CD-RW to
another host which doesn't have an operating system which includes an
embedded UDF reader or one hasn't been installed, you'll need to drag
along a UDF reader install program (I remember a download for one from
Adaptec, from whence Roxio originated so it may now be at Roxio, and I
suspect there is one provided by Ahead or maybe they just have you use
the one from Adaptec). Once a CD-RW is formatted for UDF, it cannot be
used with CD burning software (until you completely erase the CD-RW).
