I am using abCd (v 1.3) packet writing software on my Windows 98
computer,
but I have other computers a lap top with Direct Cd 5 and windows Pro.
2000
and Windows Xp. as other computers.
I would like to be able to write and read on all of the computers and
operating systems. What should I do?
I think abCd software can't be used on Windows Pro 2000 and Windows XP
right?

I would like to use a Packet type software which is capable of writing
and reading on all operating systems. Are there any freeware packet
writing softwares around which I could use on all operating systems?
If so where could I download them?


And in regards to udf file? If you have any udf reader file in
C;\windows\system\iosusbsys it should be able to read all types of
packet writing software right?

What about Windows Xp and 2000 Pro. and Me?
What direectory is the udf file located?

BTW can one make a diskcopy of an already formatted cd-rw disk with
data on it
and use it. It would be quicker then trying to format a new disk and
putting the same data in it, right? By doing so I will still be able
to use it like the original disk. Can delete files and get back more
disk space right?


BTW does Prassi still support abCd packet writing software.
Do they have it for Prassi DVD software for DVD-RW disks?

I understand Veritas Software company(sp.?) suppose to take over
Prassi?
Where are all the download upgrades for Prassi like Primo Cd and abCd
softwares
where we can we download? They don't even give any links on their site
as to
where one can download? What type of support is this?


Well, you've strung up a slew of questions; I'll try to answer those I
can but you'll need help from someone who knows more about abCD than I do.

In a perfect world, all packet software would comply with the
specification and any reader would read the results of any writer.
Similarly, you could begin a session with one program and continue it
with another.

In the real world, most packet-writing software historically has not
followed the spec and therefore has been inconsistent with some or all
of the others. When I used UDF, I ran DirectCD; one of its virtues was
that it was compliant with the spec.

The UDF reader on any fixed-length packet disc formatted with a recent
version of DCD will read most discs written in fixed-length packets or
variable-length closed to UDF 1.5. However, you can install only one UDF
system on any one OS, so you cannot use it on your abCD system.

AFAIK, current DCD is interoperable not only among Windows OSs but also
with a variety of Mac OSs.

UDF is not a file but a filesystem. It operates by extending the native
filesystem of the OS. It is not a file but a collection of files
installed at boot; that's why you cannot have two UDF products in one OS.

There is software which will duplicate a UDF disc. Because of the fault
handling of the fixed-length format, the result may be useless or worse
- and there will be no warning if it is.

Please read the basics of UDF in one of the usual references: the CD-R
FAQ or the primer at my WWW site.
