I noticed a discrepancy. When SoftPerfect RAM Disk creates exFAT file system on a 25 GB drive, there are about 50MB less listed in Free space and Capacity in disk properties than when I format the file system with Windows.
The reason for this space discrepancy is that the exFAT support was implemented in our RAM Disk before Microsoft published exFAT specs. So the implementation was mainly based on educated guesswork and experience, and to be on the safe side we allocated more space for file system structures.
Now that MS has published the specs, we reviewed the code and implemented a more compact FAT table. In our tests, there is now a bit more space available when formatted from RAM Disk comparing to Windows format, as shown in the screen shots below.
Thank you very much for the quick reaction and the detailed explanation of the behaviour. I have tested the new version and now I even have a little bit more memory than if I had formatted with Windows.
