I'm new to Truecrypt so I didn't quite get the hang of it yet. So, I started experimenting by creating a "standard", not "dynamic" 5MB file container and another one 10MB both are NTFS filesystem, AES encryption algorithm, and RIPEMD-160 hash.
However, when I checked the properties in the empty mounted volumes, I found that the 5MB had 2.97MB of used space, and the 10MB had 3.72MB of used space. Even though both were completely empty.
I tried using windows formating (quick) on both, nothing changed.
I know that NTFS file system uses some space for mapping, but 2.97MB out of 5MB seems like ALOT compared to normal NTFS and inefficient. If larger containers are created and a similar ratio of used space is maintained, I'd be losing alot of space.
What is the cause of this, and is there a way to avoid it?
