What is the largest volume that I can create?
On a PC, FreeOTFE has a theoretical maximum volume size of 2^64 bytes (16777216 TB; 17179869184 GB). For fairly obvious reasons, I have not had the opportunity to test a volume this size! In practice however, although partition based volumes may be able to realise volumes as large as this, file-based volumes may find that limitations with the filesystem that the volume file is to be stored upon may prevent this limit from being reached. For example, a FAT32 drive cannot store a volume file which is 4GB or larger. In practical terms, this means that the largest volume you can create on a FAT32 filesystem is 3999 MB. An NTFS formatted drive can store volume files much larger; in excess of FAT32’s 4GB limit, and up to FreeOTFE’s maximum size stated above. On a PDA, the largest volume supported is 2^32 (4GB). This is due to limitations with Windows Mobile.
