AllSync & AllDup

In many cases, if the name/size are the same, comparing all bytes is overkill - it would be nice if there was a faster subset comparison, like 10% of file at random positions or evenly spaced positions in blocks...

(Possibly even less than 10%, I am watching it compare 18-21MB jpg files from a WiFi connected PC and it is taking seconds per file out of 12,470 files. Perhaps a sliding scale based on file size or a maximum comparison bytes or blocks.)

A File Content search, Byte by Byte method, gives you the option to "First compare a data block at the end of the files".
