That is the wrong approach to solving the problem.

You should find out why your app needs to write to this location, and remove that need.

strace -o /tmp/log /opt/myapp/myapp.bin

will write all kernel calls to /tmp/log. There you can look for a call
   open("/opt/myapp/something", O_CREATE||O_WRITE) = -1
to see what file it attempts to write.
