    I use veracrypt for my OS, how do I expand my system volume? I byte by byte copied my old hdd to a bigger hdd and now I have an OS partition that doesn't take up the whole drive.

    I'm also interested in an answer to this question. This should be important for a lot of users who move their systems to a larger drive.

    Does VeraCrypt support expanding encrypted system volumes?

    At the moment I'm booting to the new system, decrypt the system partition, expand the decrypted system partition outside of VeraCrypt and then encrypt it again after the expansion.

    Is it correct to do it like that?

    I'm also interested in this. I suppose it might be possible by modifying the header on the new drive using an hex editor.
    See https://www.veracrypt.fr/en/VeraCrypt%20Volume%20Format%20Specification.html
    I'm not sure how that would be done since those offsets (100 and 116) are encrypted and there is a checksum on 252. Perhaps it could be edited with the OS booted and encryption would be automatically applied?

    I don't want to go the decrypt/encrypt route since data might be left behind on SSDs.
