v1.01.068
By selecting files in the list, when a file was non-writable, because used by Windows, Defraggler skipped it, also by clicking on Defrag Drive.
v1.01.073
Now, by selecting files in the list, instead of skipping the file, the software stops ( 'Defrag Failed' ) and not defrag the other files selected.
But by clicking on Defrag Drive, it's skipping normaly.
