I made a CD of my address book & when I tried open it I got the
following message. “The address book has been locked by another application.
Please close the other application & try again later” I Googled the problem
& I did as Microsoft suggested & made sure the “Read only” box was
unchecked In all address book files. It was. Still no luck. Any help would be
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

There are two ways that a file can show up as being “read-only”:
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 you’ll get something like
This example shows the read-only flag as being set, so this file cannot be
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 can’t alter the contents of a CD-R once burned, they’re read-only
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
But, naturally, there’s 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 “copies” 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, it’ll simply be the read-only attribute on
the file that has been set. Right click on the file, click on
Properties, uncheck the “read-only” attribute, and
hit OK. You’ll need to do that for each file you copied and/or
need write access to.
