Typical examples are BC92Ed01 and BC92Em01.
Typically the sizes range from 35 bytes to 10 kByte.
I have far more of these files than any other files in some partitions.
I find them especially in an Acronis Disk Management User data folder which Acronis neglected to remove when I uninstalled it.
They also appear in a portable CrystalDiskInfo application and they have identical date/time stamps to when I unzipped that application.
They also appear in my Palemoon browser cache.
Is this "Flotsam and Jetsam" that comes in with the Internet
