Yes. 7,714 files containing 182 Mbytes of data require only 1 minute 57
seconds, but moving them to another folder on the same disk takes about 10
seconds without the "Real-time protection"! This is 13 times slowing down!
Also, what is the point to check files (while moving) which already have
been checked?
