There seems to be a mismatch between the RAM Disk application version and its driver version. For example last year, when I upgraded v4.3.3 to v4.4.0, I noticed the driver version did not change.
And now, when I installed RAM Disk v4.4.3, I also see a discrepancy amongst its files version numbers. For example, the RAM Disk .exe file is correctly version 4.4.3, but its .dll and .sys files are still version 4.4.2.
