I made a CD of my address book & when I tried open it I got the
following message. âThe address book has been locked by another application.
Please close the other application & try again laterâ I Googled the problem
& I did as Microsoft suggested & made sure the âRead onlyâ box was
unchecked In all address book files. It was. Still no luck. Any help would be
greatly appreciated.
The problem, I suspect, is that there are two types of read-only.
And a program that requires that files NOT be read-only wants it both
ways.
Become a Patron of Ask Leo! and go ad-free!
There are two ways that a file can show up as being âread-onlyâ:
-
The read-only flag can be set for the file. Every file on disk has this flag
and of course it can be either on or off. In Windows Explorer, right click on a
file, click on Properties, and youâll get something like
this:
This example shows the read-only flag as being set, so this file cannot be
written to. -
The file can be on read-only media. ALL files on read-only media
appear as read-only. And CD-R is a read-only media. The individual property, above, may or may not indicate
read-only, but because you canât alter the contents of a CD-R once burned, theyâre read-only
regardless.
to your hard disk, the files will still be marked as read-only.
What typically happens is that a program that tries to use the file will
attempt to open the file and ask for the ability to write to it. If the file is
read-only, for either of the above reasons, that open will fail.
The confusing part is that this attempt to open can fail in ways that are
very similar to the failure that happens if another program has the file open.
The net result is the slightly confusing error message you receive.
So, what to do?
Since the CD will always be read-only no mater what you do, you need
to copy the file or files to your hard disk and open them from
there.
But, naturally, thereâs a catch.
When files are copied the program you use to copy them sees that the files
are read-only. Unless you tell it otherwise it âcopiesâ the read-only
attribute with the files. That means that even after copying the files from CD
to your hard disk the files will still be marked as read-only.
But this time, on your hard disk, itâll simply be the read-only attribute on
the file that has been set. Right click on the file, click on
Properties, uncheck the âread-onlyâ attribute, and
hit OK. Youâll need to do that for each file you copied and/or
need write access to.
Errr Leo, itâs certainly not necessary to âdo that for each file you copied and/or need write access toâ (i.e. to remove the âReal-onlyâ attribute); one can simply select more files and/or folders and do that only once for all the files/folders together.

The read only message will not allow me to copy files to my computer â THAT IS THE PROBLEM!!!!!!
Dear Leo,
When I burn CDs (RWs) with data files (MS Word) for the first time, everything is fine and I can open the files and work with them. I save the disk to be read on (or be compatible with) all âCD-ROMS.â However, when I try to access the files on the CD the following day, the CD is not recognized. The CDs work fine on other PCs.
I thought perhaps the CD-ROM wasnât working, but it works perfectly when I insert a CD that I have not burned, but purchased or one that has been burned by someone else.
Thanks for your help.

I finally copied and pasted onto an email to myself all the information that was on my CD-RW disk as âread onlyâ. Then when I tried to delete that information from the CD-RW disk, it will not let me delete it. How can I delete what I donât need anymore on the CD-RW disk?
IHAD PICTURES MADE OF MY KIDS AND THEY PLACED
THE PICS ON A CD SO I COULD PRINT MORE AT HOME
WHY DOESNT IT OPEN WHEN I PUT THE CD IN THE DRIVE? I LOOKED IN THE CONTROL PANEL AND IT DOESNT EVEN SHOW I HAVE ANYTHING IN THE DRIVE TO OPEN????
How annoying this is. I have XP and cd/rw drive and it is maddening that I canât just copy whatever I want to the CD without big brother watching and putting stops in my way. First Iâm forced to put all the files into a temporary spot on my hard drive, and then it will âallowâ me to copy but then it makes everything âread-onlyâ. You stated that cd-r is always read only. Is that ALL CD/Râs, RWâs, DVDâs â Iâm confused.
Joyce â
CD-R, DVD-R are writable only once. Once data is burned or written to the -R optical media it is forever-after only readable. No further writing is possible. This is the physical nature of the media and not a plot by the government or âbig brotherâ to take away all of your freedoms.
Once data is written to the disc there is no method to âdeleteâ or change the data in any way.
The only way to change or âdeleteâ the data is to physically destroy the disc with methods such as shredding in a paper shredder. Most shredders these days come equipped with the ability to shred optical discs.
CD-RW and DVD-RW discs, on the other hand, are rewritable and can be burned many times. Data files on those types of discs can be âdeletedâ in the sense that the files can be over-written with other data. Some DVD-CD burning programs even support âerasingâ an -RW disc by writing blank data onto this media but wonât be able to do anything with an -R disc.
None-the-less, the Windows file system NTFS will still see the files on any optical disc as âread onlyâ because NTFS doesnât natively support on-the-fly writing to optical discs, the way it does with HDs and USB drives. Thatâs why we always have to use a third-party software program to burn CDs and DVDs. Thatâs also why we canât open a file contained on a CD, edit the document and save the changes. Windows has no mechanism for doing that. The file has to be copied to a non-optical drive and changed from that location, then reburned onto the -RW or to a new -R disc.
This inconvenience is the main reason I havenât used CDs or DVDs as backup media for years, since USB drives became available. Thumb drives are much easier to use and far more reliable than CDs plus the capacity for storage is much higher. I even had my data backup USB thumb drive go through the laundry but after I left it alone to dry for 24 hours it still worked and all of my data was still intact. Try doing that with a CD or DVD backup. I would say that using optical media for archiving purposes is a thing of the past.
â[W]hen I tried to delete that information from the CD-RW disk, it will not let me delete it.â
@Ursula: I canât delete files, either. I can only overwrite them (on CD-RWs). I think thatâs the nature of the beast.
Whoa! Looks like Tom R beat me to the punch by a few minutes!
As to the problem of another program apparently using the file â get the freebee âunlockerâ which halts all invisible activity related to the file and lets you copy/move/erase/rename it on a HD.
Erasing/rename/move isnât possible on a CD-R as mentioned as its set in âplasticâ :)
I use USB FlashDrives for some archives, and CD-Râs for others.
Archives containing files which are expected to be âpermanentâ and to seldom change, or which are expected to contain fixed or âstandardizedâ versions of certain files â files which I wouldnât want to change â Iâll put on CD-Râs or DVD-Râs, exactly and precisely because they cannot be deleted or changed once written to.
Other archives â those which are not expected to be of an âunchangingâ nature â Iâll put on an USB FlashDrive, since they have larger storage capacities, are read/writeable, often have faster access times, and can be formatted for NTFS (a thing you cannot do on a CD or DVD unless you use a âvirtual drive containerâ, such as TrueCrypt permits).
In this way, I get the best of both worldsâŠÂ      :)
