Set the virtual drive size

[ashotjanibekyan]

By default, when I create a new drive using IDokanOperations.CreateFileSystem, it has the same total and available size as my computer. How can I limit the size?

The total and free space shown for a virtual drive depend on what you return in your GetDiskFreeSpace method implementation.

Thanks. What is the difference between freeBytesAvailable and totalNumberOfFreeBytes?

[LTRData]

They are usually set to the same values. But principally, totalNumberOfFreeBytes is amount of free space (not in use) in the drive, while freeBytesAvailable is amount of free space available to the requesting user. It can be less than totalNumberOfFreeBytes if there is some kind of quota-based policies active, or if there are other technical reasons why not all unused space can be used.
