Al Smith

I'm trying to delete a file from a CD-RW.

I get an access denied message.

The R attribute is set.

I get Access denied when I enter the dos command

attrib -r f:\filename.

How can I delete this file?

There is a 7 meg file on the disk. I can't write anything to
the disk and I can't delete the file.

Hallo Al Smith,

I'm trying to delete a file from a CD-RW.
I get an access denied message.

A CDROM is not a random access device. Basically you can only burn
read only file systems to the cd-rw. Because you have an RW it is
possible to remove the file system and replace it by a new one.

Using software line Nero burning rom it is possible to update your
CD-RW and thus remove files form the cd. But to the best of my
knowledge the normal windows explorer lacks this feature.

If you burned the cd as a data cd then you have to erase the whole cd at
once using the same software that you burned the cd with.

You will need to transfer all the contents of the CD back to your HDD and edit them there and then format the disk(erase it) and then rewrite everything you want back to the CD. That's the only way I know of doing it. Good luck

These answers aren't strictly true. It all depends how you originally burnt
the data to the CDRW disc. If you used Windows built in burning you shouild
get a third party burning software, I use Nero 6 but a lot comes down to
personal preference. The easiest way would probably be to do as The Unknown
P said and copy the contents of the disc back to the hard drive then reburn
the data to the CD. You don't need to format CDRW discs. You only need to
reformat (or format) if you want to use packet writing software like Nero's
InCD. Packet writing turns the CDRW disc into something akin to a big floppy
and you can drag and drop files to the disc. If you don't want to format the
disc you can do multisession discs where the data stored on the disc is kept
and the contents table (the table that stores the file names on the disc) is
updated. This way you can rewrite untill the disc is full.

There are plenty of good web sites dedicated to burning CDs so do a search
on google and you will soon get the hang of it. If you haven't formated the
disc just put it in your rewriter and click erase and it will erase the
disc. This is NOT formating it just erases the data so you have a blank
discs again. What you do all depends how you burned the disc the first time
and how quickly you pick up CD burning. Read the help files that come with
whatever burning program you choose.

Wow, you waited an entire two hours and five minutes before blathering
out you post again. Did you even look back and see your question was
already answered in your last post?

Just put it in my rewriter?

I can't find my rewriter. Do you happen to know where I left it?

I chose Win XP. I have read everything. It doesn't explain what to do when
Windows says access denied.

Yes. It wasn't, at least not correctly

Okay, here's a lesson in XP's burning function.

While you can write individual files to a CD-RW disk and add them as you go
along, you cannot selectively delete, you can only erase the disk which
removes everything.

If you use XP's built-in burning function, you cannot treat this disk as you
would your hard drive or a floppy disk. This requires packet writing and XP
does not support that function natively. This
requires third party software such as the Direct CD component of Easy CD
Creator, www.roxio.com or the InCD component of Nero, www.nero.com.

Check the web sites for version compatibility with XP as well as compatible
CD-Writers.

So, to sum up, if you are using XP's built-in CD burning function, you
cannot delete an individual file, you can only erase the disk and start
over. You cannot "move" a file from the CD to your hard drive but you can
copy a file from the CD to your hard drive.

Hope that helps.

Wonderful! How do I erase the CD-RW disk?

Place it in the drive, when the lights on the drive stop blinking, right
click the drive in Explorer and select erase disk.

Does that Erase do the same as easy CD and/or Nero or does it also "format"
the cd in some fashion like DirectCD or InCD do?

For lack of a better term, it does a format of sorts but it is different
than the format for Direct CD and InCd which are formatting for packet
writing.

If you later wanted to use this disk for either of those, the disk should
first be erased using, Direct CD's case, Easy CD Creator or the erase
function in Nero to return it to its blank state before trying to format for
packet writing. If you don't do that first, they will format but you will
get a report of errors and the disk will be essentially unusable until you
can first erase it. If you try formatting first, it may lock up your
burner.

I was just more interested in if it was a more immediate way to erase
cd-rw's over starting one of the burner programs to do it instead. I never
do anything but the standard Mode 1/Mode2-Joliet type thing.

Wonder if "we" shouldn't now refer to that as "blanking" a cd now that erase
is ambiguous :)

If you made the CD with the inbuilt burning, it does not burn files
individually but as a batch in an 'ISO session'. CD-R style. You
cannot delete or edit or overwrite them - all you can do is erase the
disk as a whole. Read more at http://aumha.org/win5/a/xpcd.htm

Good netiquette suggests you wait a minimum of 24 hours before
reposting. If posting sooner than that, you are considered rude.

Remember this is basically a peer support newsgroup. Most people here
have regular day jobs and check the group maybe once/day. Give them a
chance to answer before reposting.
