Some time back i moved from vmware to virtualbox, and am currently
wondering if there are some old vmware files i can remove. Virtualbox uses
the old vmware disk files, so first i checked via atime and lsof.
Why does atime not show all the files that lsof shows were open?
Steps were;
1. start vm
2. create and save dummy file in vm
3. run lsof on vm PID
4. shut down mv
5. run find to see which files were accessed
# lsof -p 2299 | grep 'VIRTUALS/Win-10-x64'
