I have a new Dell (3months) with Sonic software handling a DVD/CD combo rewrite drive. Whenever I back up for example Quickbooks, the result is a read only file. Any idea what I am doing wrong? In the past I was able to access the backup file to verify its accuracy. Thanks in advance for you help.

"Subject: [3-57] How do I clear the "read-only" flag under Windows?

If you write files to a CD-R with conventional recording and then try to copy them back, under Windows the files will all have their "read only" flags set. This can be annoying for documents you want to update.

The files aren't written to the disc as "read only". There isn't any such permission flag in the filesystem. They're simply presented that way by Microsoft operating systems. Mac OS deals with this in a nicer way, showing unlocked files on write-protected media, rather than the dopey Microsoft approach of showing write-protected files on unlocked media.

You can avoid this situation entirely by using packet writing (where you just copy files to the disc like a big floppy, e.g. with DirectCD), which preserves the file attributes, or by using backup software, which will restore the files to their original state. Stuffing the files into a ZIP archive works too, but may be less convenient than other approaches.

If you've already got the read-only files, changing them back to read-write isn't too hard. Some approaches:

If you're using Win2K or WinXP, right-click on the top-most folder(s), and un-check the read-only box. You will be asked if you want to apply the change to all files and folders in the folder. Say "yes".

For DOS or older versions of Windows, from a DOS prompt run "ATTRIB -R *.* /S" on every subdirectory with read-only files in it.

If you prefer a Windows application, try "ReadOnly" from They also have a more sophisticated application called "FlagRASH".

If you can boot into Linux, su to root, mount the volume as vfat, cd to the directory in question, and do "find . -print | xargs chmod +w" to enable write permission for all files in the current directory and in all subdirectories. If you've got the GNU utilities, use "find . -print0 | xargs -0 chmod +w" instead, because it'll work correctly on files with spaces in the names. (Of course, if you're a Linux user, you could just use mkisofs with the appropriate options and have Rock Ridge file permissions that match the originals, but this is a Windows question.)"

Check at the web site. There has been some discussion at another board about the incompatibility between Quicken, Quickbooks and a variety of backup software.
