Which is why the development of online and offline BACKUP programs is so important. A good example is that "DOS" along with some other software when booted and run may actually be the right answer for this old OS. Microsoft didn't provide an API call to "unlock" a file in use so you can search for a very long time to fix this issue, but I know it too well.
FOr example, the KNOPPIX CD when booted can use K3b to create file backups.
Best of luck in your search, but since it wasn't solved in 9 years with "online" methods, then its unlikely you will fix it.
OS is Win98SE
Browser is IE6_SP1
My antivirus app provides updates (signature files) very frequently! Unfortunately,
all it leaves behind is a text file showing the version number of the latest update.
I like to know which files have been changed, deleted, or modified. I used one of the
many apps that will scan a directory and copy only those files that have been altered.
I discovered that one important file could not be copied. It was locked, even though
the antivirus app was not running.
Is there a way to unlock this file. I found a small applet called CopyLock that probably
would do the job, but I would like to unlock the file so when it is modified or overwritten
it can be copied by my backup application.
