Helping people with computers... one answer at a time.
CD's are great for backup and storage. However CD-R's are not so good for files that you need to directly access from certain programs.
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 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.
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:
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 can't alter the contents of a CD-R once burned, they're read-only regardless.
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, 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.
