I created a "Dynamic" VeraCrypt container of size 10 GB, i.e. it will grow when the usage needs it.
As it's initally empty, in reality it takes less than 100 MB on disk.
Why does it still take a few minutes to copy with Windows Explorer to an external USB HDD (normal time for 10 GB with my USB2 device), rather than a few seconds, as the file in reality takes less than 100 MB?
Why does it copy the full 10 GB whereas only < 100 MB are used?
